upper quest
Example of what I’m running into? Not really sure what I’m doing wrong as it matches my guide
viscid bough
please don't use images of screens
viscid bough
looks like you're running it incorrectly
viscid bough
Wasn’t sure how else to show it
it's text, just show it as text
upper quest
I can’t tell what’s incorrect? Everything matches exactly how my guide shows it
viscid bough
looks like you're running it incorrectly
how exactly are you running it?
upper quest
And I watched a yt video and it shows it the same as well
upper quest
I’ve just been pressing the little green play button that says “run beginning.java”
upper quest
have you tried just running it manually
I know I probably sounds completely dumb rn lol but trying to teach myself completely
viscid bough
the statement itself isn't dumb but... what does that mean? how is that answering my question...
upper quest
Idk what you mean by running it manually lol
On my errors it says “class ‘beginning’ is never used:1”
viscid bough
Idk what you mean by running it manually lol
via the command line
using the run button is having the ide run it
do you have java installed
upper quest
intellij is what I’m using
And ye I have Java installed
I tried to run manual and it says “nothing to show”
mighty current
hey
go to the file at the top left
click project structure
then check if you have java setup in intellij
upper quest
then check if you have java setup in intellij
Is that just under the project field or one of the other ones
It says project, modules, libraries etc
mighty current
ctrl + alt + shift + s
mighty current
in project it says SDK:
viscid bough
I tried to run manual and it says “nothing to show”
?????
open the command line, navigate to the folder where you have that file, and run java Beginning.java
mighty current
manually i think they meant
upper quest
in project it says SDK:
SDK it says “openjdk-19 Oracle openJDK
mighty current
good follow what chris says
upper quest
open the command line, navigate to the folder where you have that file, and run ...
“Error could not find or load main class Beginning.Java”
viscid bough
you skipped a step
viscid bough
navigate to the folder where you have that file
upper quest
Okay I’m there
viscid bough
in the command line.
if you're in the right place, you should be able to run (windows: dir | *nix: ls) and see Beginning.java in there.
viscid bough
tbh i think the ide fucked you over a bit on this one
just to be clear; ask about anything you don't understand. i don't know you, i don't know what level of background knowledge you have
mighty current
“Error could not find or load main class Beginning.Java”
can you show me the error now when you run in the terminal
upper quest
can you show me the error now when you run in the terminal
PS C:\Users\NESuser\IdeaProjects\beginning> java Beginning.java
Error: Could not find or load main class Beginning.java
PS C:\Users\NESuser\IdeaProjects\beginning>
viscid bough
according to your uh image, your file is in a project folder, main/src etc
upper quest
just to be clear; ask about anything you don't understand. i don't know you, i d...
Yeah sorry, I’m extremely confused lol
viscid bough
use cd folder to "open" into that folder
upper quest
according to your uh *image*, your file is in a project folder, `main/src` etc
Yeah that’s what my guide did. It said new project
viscid bough
use dir to see the contents of the current folder
upper quest
How do I get back to that there
Where it shows all those
Bc it said that before I did new project
upper quest
Mine shows this
mighty current
there should be like a small button thing called Project
upper quest
Sorry for pics
mighty current
you cant run this
upper quest
But it’s so needed lol
viscid bough
But it’s so needed lol
please just stop
upper quest
Okay did
mighty current
click new project
viscid bough
discord browser exists
snipping tool exists
upper quest
There’s one that say new project and one that says empty project
mighty current
the new project
it will be like this
click it and choose language : Java and build system: Maven
viscid bough
bruh why is js listed alongside the others 💀
mighty current
no idea
upper quest
upper quest
okay I did that
mighty current
name change to firstApp
upper quest
Done
mighty current
create
viscid bough
oh you have different casing in your classname and filename
mighty current
go to main
upper quest
oh you have different casing in your classname and filename
nah I used same
mighty current
and click the run button on the top right green one
viscid bough
nah I used same
uh clearly not?
upper quest
uh clearly not?
I switched it, I had capital B
viscid bough
ah k
upper quest
And just tried lower case to see if it’d work
upper quest
and click the run button on the top right green one
Okay I clicked run and it worked
But don’t I have to create new project to start coding something else?
mighty current
this is a new project
upper quest
Oh gotcha so just delete this and try to code my beginning thing again
But for public class I need to put Main?
mighty current
no need
type main in intellij
it will make it for you instead of typing whole thing
mighty current
you need public class Main {}
always
inside those {} is your code
do mooc.fi to learn properly
upper quest
ahh gotcha
mighty current
this way you wont understand java or intellij
viscid bough
