why is there separate file type for interfaces?
remote swallow
public interface
echo basalt
Regardless of implementation, I get the interface
remote swallow
public class
storm crystal
Regardless of implementation, I get the interface
whats .class
rotund ravine
why is there separate file type for interfaces?
There isn’t
echo basalt
and call the method defined on that interface
quaint mantle
Hell nah bros using notepad++ for usre
echo basalt
Which the implementation.. implements
storm crystal
and call the method defined on that interface
which is blank
empty
you still need to make the code in that method
echo basalt
The interface defines that the method exists
And it is up to each implementation of the interface to define its functionality
The mongo implementation grabs the data and sticks it in a mongodb database
storm crystal
but inteface is literally made out of empty shit
echo basalt
The mysql implementation grabs the data and sticks it in a mysql database
storm crystal
how is it supposed to tell how empty shit is supposed to work
echo basalt
The interface is a common contract that they all follow, so that regardless of implementation I'm calling the same method

Roast opportunity
echo basalt
you will make a class
storm crystal
what advantage is in using interfaces
echo basalt
that implements the interface
you can do it later
You can rely on interfaces while you design your program's architecture
rotund ravine
We will just repeat what we have already said lol

pseudo hazel
its mainly so that other parts of the code dont have to be a pain in the ass when interacting with the classes that implement interfaces
storm crystal
then why not just not implement them at all?
slender elbow
interface Storage {
void saveItem(ItemStack)
}
class SqlStorage implements Storage {
// implement saveItem for sql
}
class YamlStorage implements Storage {
// implement saveItem for yml
}
then in your plugin you use Storage but it can be either SQL or yaml
this is called abstraction
pseudo hazel
if you dont see the benefit you either dont understand, or have not made big enough code to see why its useful
storm crystal
interface Storage {
void saveItem(ItemStack)
}
class SqlStorage implements Sto...
why not make two methods in storage for db and yaml and use the one im interested in interchangably
slender elbow
because you want to use one kind of storage that is determined at startup
and then you aren't doing if (storage == sql) savesql else saveyml
every single time
storm crystal
I wouldnt
id just do storage.saveItemSQL or storage.saveItemYaml
id just do two methods for it
and use whichever one Id need
storm crystal
yeah, I can just make one instance of Storage, pass it to whatever class needs it and just cast whichever method I need
I wouldnt care about the other one
slender elbow
yes
and wherever you need to save the item just call saveItem on the Storage instance, where you use it you don't need to care what kind of storage it is
quaint mantle
id just do storage.saveItemSQL or storage.saveItemYaml
You opening class for modifications
storm crystal
You opening class for modifications
aand?
quaint mantle
Like if you want to remove the "yaml" saving most of parts of app just give compile error.
And you have to refactor it.
storm crystal
isnt programming about rewriting
slender elbow
no
pseudo hazel
not if you do it right
slender elbow
good code is that that has the least friction to changes elsewhere
it's good to maintain because you don't have to go all over the place adjusting one small thing
storm crystal
whats the point of abstraction
why would I not give access to data
to someone
well to something

You mean encapsulation?

Here are some links to get you started on learning Java:
- https://www.codecademy.com/learn/learn-java
- https://www.sololearn.com/learning/1068
- https://www.learnjavaonline.org/
- https://programmingbydoing.com/
- https://docs.oracle.com/javase/tutorial/java/index.html
The last one is the only official one, however some of those concepts assume that you already know a bit about programming.
storm crystal
You mean encapsulation?
idk what it is
why is it so important to not let other classes or other shit know about stuff
what if that class happens to need to know about something
rotund ravine
Example?
pseudo hazel
stop spamming learnjava, it has no meaning at this point
eternal oxide
Bukkit gives you access to a Player but it doesn;t expose the whole Map of Players
eternal oxide
stop spamming learnjava, it has no meaning at this point
While he refuses to read any of it it has meaning
storm crystal
im just saying
pseudo hazel
not if it gets ignored
storm crystal
While he refuses to read any of it it has meaning
you ever been to school?
eternal oxide
then that end up being the only answer
eternal oxide
at some point he will stop askign basic questions or actually READ
eternal oxide
you ever been to school?
Have I been to school? odd question
storm crystal
Have I been to school? odd question
let me explain
rotund ravine
they take it unnaturally seriously
Elgar getting banned i guess
storm crystal
the more teacher pushes you to study stuff the less you are inclined to do it
rotund ravine
Oh, sooo
storm crystal
Elgar getting banned i guess
no I just didnt want him to actually say "yeah I am" cuz that could actually get him banned
😭
rotund ravine
the more teacher pushes you to study stuff the less you are inclined to do it
If we tell you to write plugins you will eventually stop and leave?
eternal oxide
the more teacher pushes you to study stuff the less you are inclined to do it
only an idiot takes that approach
storm crystal
only an idiot takes that approach
damn 80% of students must be such idiots
eternal oxide
yes
storm crystal
out of 13 years of education so far Ive rarely, rarely ever saw people who get motivated when teachers tell them to study this or that, instead of getting demotivated or starting asking questions what is it even for
storm crystal
If we tell you to write plugins you will eventually stop and leave?
ah so you want me to leave, then no
eternal oxide
If a teacher keeps telling you something and you refuse to listen, at some point the teacher gives up as you refuse to learn
echo basalt
Bros stubborn
pseudo hazel
okay so what is this discussion even about
storm crystal
If a teacher keeps telling you something and you refuse to listen, at some point...
then they dont get paid no more that's overstretching
echo basalt
Interfaces and polymorphism
storm crystal
the more you are pushed towards doing something most of the times you show innertia unless you got a good reason to do it and are motivated enough
eternal oxide
then they dont get paid no more that's overstretching
teachers don;t get paid for you learning, they get paid to teach
storm crystal
like spamming ?learnjava for n'th time wont do stuff, at this point I consider it as a way for someone to deliver their bad blood towards me and simply ignore it

Great permission
storm crystal
I have this
public interface AnimalStuff {
void breathe();
}
public class Animal implements AnimalStuff {
public void breathe() {
//breathes w/e
}
}
class Main {
public static void main(String[] args) {
Animal cow = new Animal();
cow.breathe();
}
}
and now
how do I make another animal
that would breathe differently
with interfaces
storm crystal
Animalstuff shouldn’t exist
blame w3schools
pseudo hazel
interfaces with 1 implementation are literally useless
vocal cloud
pseudo hazel
it would be Animal implements Breathing
and then your cow would extend Animal
and if you want you can make another animar that breathes differently
but you can also make a Human implements Breathing
storm crystal
thats not even the point w/e the semantics
pseudo hazel
assuming humans arent animals
rotund ravine
I feel like animal should either be abstract or the interface considering animals doesn’t breathe the same
@storm crystal do you know what an antonym is?
storm crystal
yes and relevance?
pseudo hazel
I mean the example is just kinda bad
storm crystal
I havent asked for critique
idc how bad it is
whats the point of interface if I supposedly cant even make those methods work differently
rotund ravine
You can ur just being dumb about it
pseudo hazel
you can
storm crystal
You can ur just being dumb about it
I am literally asking a question how to do it
pseudo hazel
you can implement breathing in all subclasses f you want to
rotund ravine
Make animal an abstract class or interface too
remote swallow
are you still not understanding what an interface is for
rotund ravine
He is not

public class Pig implements Animal {

public static void main(String[] args) {
Animal cow = new Cow();
Animal pig = new Pig();
cow.breathe();
pig.breathe();
}
}
Same
storm crystal
better?
rotund ravine
Now name animalstuff animal
And Cow cow and Pig pig just needs to be Animal instead of their respective classes
rotund ravine
Why?
eternal oxide
Most basic definition

Watch me get home and record a 10 minute video

They usually name a different method to use if they’re deprecated
storm crystal
Animal cow = new Cow()
why Animal
storm crystal
helpful
pseudo hazel
you would assign it teh most basic iomplementation that you wnat to use
storm crystal
why not just make it their respective class
pseudo hazel
but in most cases it doesnt really matter I find
rotund ravine
Well the idea would be that regardless of what animal it is you can just have one method and be able to call Animal#breathe
Instead of 50 methods that does each animal
wild nexus
They usually name a different method to use if they’re deprecated
Nop ?
pseudo hazel
Well the idea would be that regardless of what animal it is you can just have on...
thats not the issue
he was just asking why it would be Animal cow = new Cow() instead of Cow cow = new Cow()

there is no reason for it imo

in here they would just do Pig pig = new Pig();

I am trying to reply to it considering the whole hour or two long convo we had

pseudo hazel
teh diff is if your pig has another method and you create it with Animal pig, you cnat use that method
rotund ravine
Though, that doesn’t breathe
pseudo hazel
unless you cast it back to a pig
storm crystal
okay so casting Animal t ype
rotund ravine
teh diff is if your pig has another method and you create it with Animal pig, yo...
Sigh
rotund ravine
Yes
storm crystal
if I casted Pig and pig had haveFunInMud() method
I could use that method
but if I casted Animal
I wouldnt
rotund ravine
Yes
storm crystal
so it just tells me what methods I can cast?
rotund ravine
No
icy beacon
If you need a pig specifically and really down bad just instantiate Pig pig = new Pig(), but if you need any animal with no quirks, instantiate Animal pig = new Pig()
It's a good practice to instantiate the lowest level iirc
river oracle
Look up how to use Java modules and then how to use them with maven and just cry its not fun it doesn't make much sense and worst of all its insanely hard to get to compile

You can survive without that. That's why
It is just a better practice
river oracle
I'm never using JavaFX again

It fucks with your other depenendecies too
rotund ravine

icy beacon
Uhh I don't exactly see why you would make a class for kills
storm crystal
Why would there be a class for omly kills
class for each data type
remote swallow
kills isnt a data type
icy beacon

rotund ravine
PlayerStats can be
remote swallow
player data is a data type
remote swallow
what illusion said about data types isnt that
storm crystal
class for kills that implements database management or behaviour or whatever you call it
you get it
and class for deaths
remote swallow
no
storm crystal
and for other shit like money
remote swallow
player stats class has the data behaviour
pseudo hazel
sounds like overkill
icy beacon
You do not need a class for every statistic
storm crystal
Illusion essentially told me that I do
icy beacon
Link the message plz
echo basalt
Here's the proper explanation because in his eyes the interface can be omitted:
An interface is a sort of empty contract class that defines the methods its implementations (classes that implement the interface) can have.
An interface can extend multiple interfaces, a class can implement multiple interfaces.
public interface Animal {
void idle(); // A method of the return type "void" named "idle" with no parameters
}
public interface Breathable {
void breathe();
}
public interface BreathableAnimal extends Animal, Breathable {
}
With these contracts, we can then create a few implementations
public class Snake implements Animal {
@Override
public void idle() { // We must override this method or make this class abstract, as the Animal interface states this method exists in all implementations
System.out.println("I'm a snek");
}
}
public class Cow implements BreathableAnimal { // This is the same as implementing Animal and Breathable
@Override
public void idle() {
System.out.println("moo");
}
@Override
public void breathe() {
System.out.println("*cow farts*");
}
}
We can then instance the classes we created as objects of the interface type, for example
List<Animal> animals = List.of(
new Cow(),
new Snake()
);
for(Animal animal : animals) {
animal.idle();
if(animal instanceof Breathable) {
System.out.println("We found a breathable animal!");
animal.breathe();
}
}
scroll up
echo basalt
We can pass as many different animal types on our list
icy beacon
I scrolled up and I did not see anything that mentioned your idea. Please link the message
echo basalt
Illusion essentially told me that I do
I told you that my solid design structure employs an interface and usually an abstract class for each implementation
rotund ravine
Illusion bad programmer? Banned

I'm sop confused on why this is happening. everything is setup right in my pom.xml, I do get code sense help when typing and no errors when actually writting the code, this only happens when I am trying to compile it to a jar file to test it. toastrpg is my custom library, and is imported from the system, lamp revxrsal is shaded from toastrpg so it comes from that.
icy beacon
Because you almost always know when you're working with a nullable object and the compiler will bitch about it if you're not careful

I've had nothing but issues with those weird modules they expect you to use
I have trouble compiling anything because I depend on things that don't use java modules
its a headache and quite frankly makes me want to never use jfx again
slender elbow
then you don't use them either

then you don't use them either
jfx doesn't work properly without java modules

just put javafx in the module path at runtime and your stuff in the classpath
that's what I do

and when I did use it, it didn't work nicely either so Jlink still failed to build

I can show how I have it set up, it's nothing special, but, yeah, it isn't maven however
I pretty much just have a separate task to invoke jpackage correctly, that's all the "special setup"

it seems like my program never goes through the first if statement for some reason

this is why you always use String#intern(), so your string equality checks are always correct

Can someone happen to me how is this visual bug can happen? The fireball always curve when I try to increase the speed of the fireball, but if it has default velocity, it will not curve, it will go straight.
rotund ravine
You hit it?
eternal oxide
nocode
summer scroll
No I spawned it with left click air interact.
Right, one sec.
@EventHandler(priority = EventPriority.HIGHEST)
private void onInteract(PlayerInteractEvent event) {
Player player = event.getPlayer();
if (event.getHand() != EquipmentSlot.HAND) return;
if (event.getAction() == Action.LEFT_CLICK_AIR) {
// get two blocks in front of player
Location eye = player.getEyeLocation();
Location location = eye.add(eye.getDirection().multiply(1.2));
Fireball fireball = location.getWorld().spawn(location, Fireball.class);
fireball.setVelocity(location.getDirection().normalize().multiply(5));
fireball.setShooter(player);
}
}
Interact probably runs before the actual hit
summer scroll
I heard that it was actually because of 1.20.2 spigot.
eternal oxide
you are multiplying by 6 so that will also increase the Y axis by 5

I tested it myself and it was fine in 1.19.4
Okay, so I need to set the Y to 0 right?

What happens if you delay it by a few ticks?
@summer scroll
eternal oxide
oh use setDirection not Velocity
rotund ravine
Delay the spawning
eternal oxide
summer scroll
I've tried using setDirection but it will not change the speed.
eternal oxide
else use the spwn method which accepts a Consumer
so you setDirection in the Consumer
summer scroll
Oh yeah you're right, I can use consumer okay.
It shoots straight but it has default speed, here's my code.
@EventHandler(priority = EventPriority.HIGHEST)
private void onInteract(PlayerInteractEvent event) {
Player player = event.getPlayer();
if (event.getHand() != EquipmentSlot.HAND) return;
if (event.getAction() == Action.LEFT_CLICK_AIR) {
Location eye = player.getEyeLocation();
Location location = eye.add(eye.getDirection().multiply(1.2));
location.getWorld().spawn(location, Fireball.class, fireball -> {
fireball.setShooter(player);
fireball.setDirection(location.getDirection().normalize().multiply(5));
});
}
}
You can compare the speed to the video I've shown above.
eternal oxide
what if you increase the 5?
rotund ravine
Do 1000 and see that’d be fun
summer scroll
Nothing happened.
eternal oxide
a normalized vector would be 1 block per second
so multiplied by 5 should be 5 blocks per second
does the value not affect the speed at all?
summer scroll
I'll try to debug the fireball's velocity.
eternal oxide
else try....
setDirection(...
setVelocity(fireball.getDirection.multiply(5))```err
summer scroll
```
setDirection(...
setVelocity(fireball.getDirection.multiply(5))```
Same thing happened, the fireball will curve.
rotund ravine
If you get the direction of the ball?
eternal oxide
I guess it does not like setVelocity, as teh javadoc says
eternal oxide
I assume he used the fireball for getDirection
summer scroll
Here, I'll show you the code and the debug https://paste.md-5.net/acufizajoh.md
Fireball Power is 15, that means I multiply the Vector by 15.
eternal oxide
getDirection of the fireball not the location when you setVelocity
oh nm, ignore me
rotund ravine
What happens if you mutiply the velocity of the fireball after a tick
eternal oxide
sysout the getVelocity.length
a vector is annoying
you just want to see its actual speed
eternal oxide
as is for now
summer scroll
What happens if you mutiply the velocity of the fireball after a tick
I've tried to delayed the set velocity, but the result is the same, the fireball will curve
rotund ravine
What you have now, but.
fireball.setVelocity(fireball.getVelocity().multiply(5))
A few ticks after?
eternal oxide
should check stash/nms and see if setDirection is normalizing your imput
summer scroll
as is for now
rotund ravine
.
eternal oxide
um
rotund ravine
I can’t click that for some reason
rotund ravine
Probably fireball mechanics
summer scroll
yeah i guess
summer scroll
A few ticks after?
Same, no matter how many ticks after.
rotund ravine
What you have now, but.
fireball.setVelocity(fireball.getVelocity().multiply(5))
Would want to see this run after a few ticks and what happens
Dang
Oh well blame legacy versions
summer scroll
The length right?
undone axleBOT
summer scroll
Well the getDirection().length() is identical till death, always 0.1
Same with sysout getDirection(), it's the same all the time.
eternal oxide
um 0.1?
summer scroll
Yes, the getDirection().length() is always 0.1
summer scroll
There is update() method, what is that?
rotund ravine
What happens if you mutiply the velocity of the fireball after a tick
. Totally
summer scroll
What happens if you mutiply the velocity of the fireball after a tick
Here's when I tried to set the velocity after 3 ticks.
rotund ravine
Rip
summer scroll
@eternal oxide I got this from EntityFireball.class. I'm not sure what it means tho
public void setDirection(double d3, double d4, double d5) {
double d6 = Math.sqrt(d3 * d3 + d4 * d4 + d5 * d5);
if (d6 != 0.0) {
this.xPower = d3 / d6 * 0.1;
this.yPower = d4 / d6 * 0.1;
this.zPower = d5 / d6 * 0.1;
}

do I just make main class for connecting to databases and class for each db management or include connection within those classes for each database
storm crystal
thats a shit ton of work
storm crystal
well I cant even download sqlite
lost matrix
There is a client side limitation for displaying velocity
echo basalt
It's bundled iwth the spigot jar
storm crystal
is it proper way of making connection method?
lost matrix
is it proper way of making connection method?
Depends on what you mean by "making connection method"
storm crystal
method that would connect to desired database with given prompt
or should I remove the prompt and just hardcode it for each database class
lost matrix
Usually you would pass all components of your jdbc url to a class and then internally concat it
storm crystal
is it proper way of making connection method?
so just how I made it?
can I just make it like that?
lost matrix
can I just make it like that?
You should get a completely new connection for every time you access the Database.
Unless its SQLite specifically.
eternal night
Well not completely new 😅
summer scroll
There is a client side limitation for displaying velocity
It's weird that this doesn't happen in version below 1.20.2 (at least in 1.19.4)
lost matrix
Well... yeah. Usually you have a bunch of connections and check which ones are valid.
eternal night
preferabl you don't do any of this and shade a proper connection pool like hikaricp

so just use method for it?
summer scroll
It does even down to 1.8
What's the limitation anyway? I have tried to multiply the velocity to 10 and 15 in the previous version and fireball shoots straight.
storm crystal
so just use method for it?
how do I make a method that would just return this particular connection?
rotund ravine
@storm crystal You would cache them
Hikari is a tool to do this for you

use ItemFlag to remove

storm crystal
do I make getter and setter for each datatype that I want to edit/set/get?
like UUID, deaths etc.
rotund ravine
You would get everything you would need in the immediate future from one connection
storm crystal
great I have empty table and I need to fill it first
:]
I cant make one method to be able to set both UUID and deaths
terse raven
follow a tutorial
of how to use databases
(depends on which database you are using?)
storm crystal
its not even about databases
rotund ravine
You can make one method to do it
storm crystal
do I make separate method for each datatype
storm crystal
so what
storm crystal
https://www.baeldung.com/java-mongodb
- I told you that I am not asking in field of databases
- Im using SQLite, duh
rotund ravine
You would have PlayerStats or smth that has each of the stats and then just have a method that saves and gets that
storm crystal
You would have PlayerStats or smth that has each of the stats and then just have...
but I am supposed to fill it first
with shit
terse raven
1) I told you that I am not asking in field of databases
2) Im using SQLite, duh
Sorry for not knowing the database you are using, if you do not specify it
storm crystal
its empty

Sorry for not knowing the database you are using, if you do not specify it
I didnt ask you for database guide at all
terse raven
I didnt ask you for database guide at all
It seemed like you do not know what you want
terse raven
so i suggested to first learn the basics
rotund ravine
Return an empty PlayerStats object
storm crystal
storm crystal
relevance?
rotund ravine
Are you broken?
storm crystal
what do I need empty object for
compact haven
you dont just add random data to the database
rotund ravine
He’s so broken
compact haven
@storm crystal explain your problem from top to bottom
storm crystal
you can either actually explain yourself or just keep saying it
rotund ravine
Like he comes off as either absolutely clueless or a troll
rotund ravine
What?
compact haven
Yes, because there's nothing there
is there a problem with an empty row?
technically it shouldn't return any row
the browser just shows an empty row, probably
rotund ravine
It should just return nothing when u try and get it
storm crystal
and I want to make a method that would fill that empty row with provided information
rotund ravine
Yes?
rotund ravine
No
storm crystal
how do I handle it
compact haven
So you want a method to insert data to a database?
storm crystal
to make one yeah
rotund ravine
You have a data object called PlayerStats that stores your rowdata
You have a method called savePlayerStats
That insers the data
Form the playerstats object
storm crystal
because I cant just make setData(UUID playerId, String data)
what if I want to update deaths
its not a string
compact haven
it would be setDeaths(UUID palyerId, int deaths)
the whole setData thing was pseudo
storm crystal
so it comes to a conclusion that for each datatype I'd have to make separate method
compact haven
they idea is setDeaths or setObject(UUID, PlayerStats obj)
compact haven
so it comes to a conclusion that for each datatype I'd have to make separate met...
Not necessarily, no.
rotund ravine
No…
rotund ravine
You have a data object called PlayerStats that stores your rowdata
.
compact haven
I personally have done it that way, yes
storm crystal
then why do you even propose it
rotund ravine
He explained it cause ur saving one single thing
terse raven
and I want to make a method that would fill that empty row with provided informa...
just make a check when you request the information if it is currently defined or not, if it isnt just return a default value, like 0 would probably be good in your case
storm crystal
just make a check when you request the information if it is currently defined or...
omw to return uuid 0

terse raven
yea
storm crystal
```java

what does Repository mean
compact haven
it's just an "interface" between your database and your code
that's what it is called in Spring, but you can call it anything you want
terse raven

storm crystal

the code doesnt solve my issue at all
its more or less what I've written so far
compact haven
it literally explains everything bro
getOrCreate means
if they don't have a row in the database with their id
then create it
and return that new row containing the defaults
i.e., the default death count, etc., all tied by their UUID which was provided in getOrCreate
storm crystal
"PlayerStats data = repository.getOrCreate(playerId);
data.getDeaths()"
compact haven
which is what I wrote, yes
storm crystal
why is there getDeaths out of nowhere
compact haven
bro
okay that's a fine question
that's called lombok and I used it because I wasnt going to write boilerplate through Discord
class PlayerStats {
private final UUID playerId;
@Getter @Setter
private int deaths;
}
@Getter just means that getDeaths() and setDeaths(int) exists inside of PlayerStats

The point is that it's standard convention to create getters and setters for properties of an object. The reason we didn't say "yes" to your question was because it was about the database
