hlllo

fierce sundial Oct 11, 2022, 3:46 PM

#

ocean yoke hlllo

bruh i need help

ocean yoke Oct 11, 2022, 3:46 PM

#

hi

#

ok

#

where do u use the method?

ocean yoke Oct 11, 2022, 3:48 PM

#

fierce sundial bruh i need help

store the maze outside of the constructer?

fierce sundial Oct 11, 2022, 3:49 PM

#

ocean yoke store the maze outside of the constructer?

sorry i mean i kinda moved on from that also hi

ocean yoke Oct 11, 2022, 3:49 PM

#

oh

fierce sundial Oct 11, 2022, 3:49 PM

#

ocean yoke Oct 11, 2022, 3:49 PM

#

ok

fierce sundial Oct 11, 2022, 3:49 PM

#

how would i create brackets around the output if yk?

#

like this

ocean yoke Oct 11, 2022, 3:50 PM

#

i think so u are doing quetion wrong

#

can u put quetion here? with full file code given

#

u are making array every time

fierce sundial Oct 11, 2022, 3:51 PM

#

sure

#

#

this is the question

#

theres a prequel before...but i gave up

fierce sundial Oct 11, 2022, 3:51 PM

#

ocean yoke i think so u are doing quetion wrong

😭

ocean yoke Oct 11, 2022, 3:53 PM

#

can u paste the code one sec

#

i can explain u

fierce sundial Oct 11, 2022, 3:53 PM

#

all of the code?

#

or just toString

#

``@Override
public String toString() {
//insert your code here. Change the return value to fit your purpose.

    String [][] dogMaze = {{"1110", "1010", "1010", "1000"}, {"1010", "1000", "1001", "0101"},{"1100", "0011", "0101", "0110"},{"0101", "1101", "0110", "1001"},
             {"0110", "0011", "1110", "0010"}};
    String thing = "";
    for (int i = 0; i<dogMaze.length;i++) {
        for (int j=0; j<dogMaze[i].length;j++) {
            thing += " " + dogMaze[i][j];
        }
        thing += "\n";
    }
    return thing;
    

}``

ocean yoke Oct 11, 2022, 3:54 PM

#

all maybe

fierce sundial Oct 11, 2022, 3:54 PM

#

idk if i can send, maybe i can send u the whole file?

#

``public class PE1 {

Maze dogMaze; 
/**
 * This method sets up the maze using the given input argument
 * @param maze is a maze that is used to construct the dogMaze
 */
public void setup(String[][] maze) {
    /* insert your code here to create the dogMaze 
     * using the input argument. 
     */
}``

#

i just really need help with the bracket stuff right now

ocean yoke Oct 11, 2022, 4:05 PM

#

public String toString() {
//insert your code here. Change the return value to fit your purpose.

    String [][] dogMaze = {{"1110", "1010", "1010", "1000"}, {"1010", "1000", "1001", "0101"},{"1100", "0011", "0101", "0110"},{"0101", "1101", "0110", "1001"},
             {"0110", "0011", "1110", "0010"}};
    String thing = "";
    for (int i = 0; i<dogMaze.length;i++) {

think+="[";
for (int j=0; j<dogMaze[i].length;j++) {
thing += " " + dogMaze[i][j];
}
think+="]";
thing += "\n";
}
return thing;

#

this works?

fierce sundial Oct 11, 2022, 4:05 PM

#

this assignment is just so hard

ocean yoke Oct 11, 2022, 4:06 PM

#

i just added thing + "]" when array started and ended

fierce sundial Oct 11, 2022, 4:06 PM

#

omgg

#

it works!!

#

thank u

#

im a bit concerned cuz the first part has a gap but ill try to figure it

ocean yoke Oct 11, 2022, 4:11 PM

#

for (int j=0; j<dogMaze[i].length;j++) {
thing += " " + dogMaze[i][j];
}
this loop is there rigt?
for (int j=0; j<dogMaze[i].length;j++) {
if(j==0){
thing += dogMaze[i][j];
}else {
thing += " " + dogMaze[i][j];
}
}

#

just add an if that if j == 0 then dont add space

#

@fierce sundial now it works?

fierce sundial Oct 11, 2022, 4:12 PM

#

one sec ill code it rn!!

#

omg

#

GOD BLESS U

#

seriously i would love a tutor for java

#

you seem very knowledgable

ocean yoke Oct 11, 2022, 4:19 PM

#

Arrays.deepToString(array).replace("], ", "]\n").replace(",", "").replace("[[", "[").replace("]]", "]")

#

no lol

#

u can use this

#

remove all lines of code

#

@Override
public String toString() {
return Arrays.deepToString(dogMaze).replace("], ", "]\n").replace(",", "").replace("[[", "[").replace("]]", "]");
}

#

this will work

#

just one one of code

#

@fierce sundial

fierce sundial Oct 11, 2022, 4:21 PM

#

😭 bruhhhh

ocean yoke Oct 11, 2022, 4:21 PM

#

arrays.deeptostring converts the array of more then 1 dimensinal to string

#

and then u can just replace the multiple array to nothing and add new lines

fierce sundial Oct 11, 2022, 4:22 PM

#

i really overcomplicated it i totally didnt know

fierce sundial Oct 11, 2022, 4:22 PM

#

ocean yoke and then u can just replace the multiple array to nothing and add new lines

ohhh okok

#

thank u so much..

fierce sundial Oct 11, 2022, 4:48 PM

#

btw are you familiar with getters @ocean yoke im still confused on a question

ocean yoke Oct 11, 2022, 4:48 PM

#

yes lol i am

fierce sundial Oct 11, 2022, 4:48 PM

#

ocean yoke yes lol i am

this guy is very smart

ocean yoke Oct 11, 2022, 4:49 PM

#

nah

fierce sundial Oct 11, 2022, 4:49 PM

#

yeah they really are

ocean yoke Oct 11, 2022, 4:49 PM

#

its just i made many things iwth java

#

if u do u would be more smart too

fierce sundial Oct 11, 2022, 4:49 PM

#

i just feel like the toString i did is not what the question asks

#

so basically i deep coppied right

fierce sundial Oct 11, 2022, 4:49 PM

#

ocean yoke if u do u would be more smart too

what things have u made??

#

fuck the assignment i have done is officially all wrong

#

fierce sundial <@895550125533962291> are u still available to help

yes say whatver

fierce sundial Oct 12, 2022, 2:49 PM

#

ocean yoke yes say whatver

also toString cant take parameters, i have to use the previous method u told me right

#

ocean yoke Oct 12, 2022, 2:49 PM

#

oh then its ok i didnt know

#

yes but there is a prameter u dont need to ?

fierce sundial Oct 12, 2022, 2:50 PM

#

yeah honestly im not sure cuz previous steps are so confusing

#

no like

ocean yoke Oct 12, 2022, 2:50 PM

#

fierce sundial ``public class PE1 { Maze dogMaze; /** * This method sets up ...

see here
Maze dogMaze;

fierce sundial Oct 12, 2022, 2:50 PM

#

i think we arent allowed to declare maze inside?

#

inside the toString

#

idk how to test the junits to see

ocean yoke Oct 12, 2022, 2:51 PM

#

u dont need to to declare anything

#

nor do u need to add parameter

fierce sundial Oct 12, 2022, 2:51 PM

#

ohh so its fine?

ocean yoke Oct 12, 2022, 2:51 PM

#

u didnt make contrusctor correct

#

u have to actually store it lol

#

in outside variable

#

the constructor basically does nothing

#

can u send whole file

fierce sundial Oct 12, 2022, 2:52 PM

#

i did it here?

#

sure

ocean yoke Oct 12, 2022, 2:52 PM

#

see objects are like it can be multiple

fierce sundial Oct 12, 2022, 2:52 PM

#

#

#

#

thats that

ocean yoke Oct 12, 2022, 2:54 PM

#

its correct what error is coming?

#

the to string can access the field

fierce sundial Oct 12, 2022, 2:54 PM

#

really

#

someone on the other thread said u cant do that so i was doubting

#

do you think the setUp code is correct?

ocean yoke Oct 12, 2022, 2:56 PM

#

i dont think u didnt did anything there

#

u are just initializing a local variable

#

do like this

#

this.dogMaze = new Maze(maze);

#

@fierce sundial

fierce sundial Oct 12, 2022, 2:58 PM

#

ohh

#

okay

#

thank u

fierce sundial Oct 12, 2022, 2:59 PM

#

ocean yoke this.dogMaze = new Maze(maze);

sorry what does this do, like dogMaze transfers its stuff to it, becomes the input parameter?

ocean yoke Oct 12, 2022, 2:59 PM

#

why did u make thing array in maze constructer??

fierce sundial Oct 12, 2022, 2:59 PM

#

😭 i changed the name from dogMaze to thing, i changed it

#

#

like changeed it bac

ocean yoke Oct 12, 2022, 3:00 PM

#

fierce sundial sorry what does this do, like dogMaze transfers its stuff to it, becomes the inp...

new Maze calls the contrustor and this.lol just is same as lol unless u have local variable of same name understood?

#

there is a object variable u are assigning it new maze

fierce sundial Oct 12, 2022, 3:00 PM

#

understood

#

okay

ocean yoke Oct 12, 2022, 3:01 PM

#

fierce sundial

what u are doing here is just making a local variable

#

is this some website?

fierce sundial Oct 12, 2022, 3:01 PM

#

its eclipse

#

i mean

#

its a homework i am doing

ocean yoke Oct 12, 2022, 3:01 PM

#

from where u got comments

fierce sundial Oct 12, 2022, 3:02 PM

#

professors

#

on what we should add

ocean yoke Oct 12, 2022, 3:02 PM

#

u are just makinga local variable

fierce sundial Oct 12, 2022, 3:02 PM

#

sorry i didnt know, thank u

ocean yoke Oct 12, 2022, 3:02 PM

#

remove full dogmaze code

#

i mean waht u are assigning local variable

#

remove the block

fierce sundial Oct 12, 2022, 3:03 PM

#

sorry the whole matrix?

#

where else would i declare that

ocean yoke Oct 12, 2022, 3:03 PM

#

paste here code of maze contructor then remove all code from the contructer

fierce sundial Oct 12, 2022, 3:04 PM

#

     * This constructor makes the maze. 
     * @param maze is a 2D array that contains information 
     * on how each cell of the array looks like. 
     */

            }
        }```

#

this is what i was doing

#

the 2d array is declared it writes

ocean yoke Oct 12, 2022, 3:05 PM

#

u dont have to make ur own string array of maze i think so u have to use the parameter right?

#

it will be wrong

#

why are u doing this try some other easy projects too first

#

u can do this but u should do some simple projects too and see how they work u will understand

fierce sundial Oct 12, 2022, 3:07 PM

#

😭 its a school assignment

#

it has to be hard cuz she gives a deadline

fierce sundial Oct 12, 2022, 3:07 PM

#

ocean yoke u dont have to make ur own string array of maze i think so u have to use the par...

she made us MAKE the maze in the beginning

#

#

#

so i assume we need to put that in welp

#

sorry its so blurry

ocean yoke Oct 12, 2022, 3:09 PM

#

public Maze(String[][] maze) {
this.maze= new String[maze.length][maze[0].length];
for (int i = 0; i<maze.length;i++) {

}
}

ocean yoke Oct 12, 2022, 3:09 PM

#

fierce sundial it has to be hard cuz she gives a deadline

how many days u got

#

lol nice i also wish i had somehting like this

fierce sundial Oct 12, 2022, 3:09 PM

#

a few days, sunday

fierce sundial Oct 12, 2022, 3:10 PM

#

ocean yoke lol nice i also wish i had somehting like this

☠️ lmfao

ocean yoke Oct 12, 2022, 3:10 PM

#

you can do this in half hour to one hour you will have to understand the quetion alos first but

#

it looks like u dont need to actually create the array

fierce sundial Oct 12, 2022, 3:11 PM

#

so the first part was just for fun lmfao

fierce sundial Oct 12, 2022, 3:11 PM

#

ocean yoke you can do this in half hour to one hour you will have to understand the quetio...

bruh

ocean yoke Oct 12, 2022, 3:12 PM

#

ocean yoke public Maze(String[][] maze) { this.maze= new String[maze.length][maze[0...

some changes i made is i actually assigned a new array to the null array or it will throw error if u access any feild then maze is the parameter and this.maze is the object field which i was talkign about because both name same u will have to use this.maze whwnever u want class object

ocean yoke Oct 12, 2022, 3:12 PM

#

fierce sundial bruh

are u sure the teacher gave u array and u have to make the array

#

u will gve the teacher with full errors lol ?? or u will test before

#

alot of error is going to come

#

can u show me where is main code

fierce sundial Oct 12, 2022, 3:13 PM

#

ocean yoke u will gve the teacher with full errors lol ?? or u will test before

lol

ocean yoke Oct 12, 2022, 3:13 PM

where the thread will star

main method

okay this makes sense

ocean yoke Oct 12, 2022, 3:13 PM

#

where is public static void main???

fierce sundial Oct 12, 2022, 3:13 PM

#

#

oh they dont have it

#

we have to use junit tests

#

i tried doing static void main it wouldnt work

ocean yoke Oct 12, 2022, 3:14 PM

#

ok then i think u dont need to make the arra

#

they will input the array when making new object of pe1

#

ok now what u have to do

fierce sundial Oct 12, 2022, 3:15 PM

#

they should have added SOME units of testing

#

oh um

#

i think i did the getter correctly

#

so now its task4

ocean yoke Oct 12, 2022, 3:15 PM

#

just comment the mazecode which u wrote by hand that one

fierce sundial Oct 12, 2022, 3:15 PM

#

which has srecursion

fierce sundial Oct 12, 2022, 3:15 PM

#

ocean yoke just comment the mazecode which u wrote by hand that one

okay sure

ocean yoke Oct 12, 2022, 3:15 PM

#

wow

#

they are complex idk why

fierce sundial Oct 12, 2022, 3:16 PM

#

yup..

ocean yoke Oct 12, 2022, 3:16 PM

#

they should learn first local variable and stuffs

fierce sundial Oct 12, 2022, 3:16 PM

#

🤣 ikr

ocean yoke Oct 12, 2022, 3:16 PM

#

do some simple projects urself

fierce sundial Oct 12, 2022, 3:16 PM

#

or maybe i wasnt paying attention

fierce sundial Oct 12, 2022, 3:17 PM

#

ocean yoke do some simple projects urself

this is 20% of my grade so i have to hustle, maybe another time😭

ocean yoke Oct 12, 2022, 3:17 PM

#

ok do another thing

#

what are more u have to do fast

fierce sundial Oct 12, 2022, 3:17 PM

#

ocean yoke Oct 12, 2022, 3:21 PM

#

i have done somehting similar

#

i was makign paint fill angortihm

#

u know fill right it will fill with the given color

fierce sundial Oct 12, 2022, 3:21 PM

#

yes i get it

ocean yoke Oct 12, 2022, 3:21 PM

#

what i did i added to a list a pixel which is nearby it

#

nearby it and added it if the color was same as middle color

#

then a called it again on the same list so that everything in list gets near by points and gets added to list

#

like that

#

and u have to add a stop thing too in recursive otherwise stackoverflow

#

did u understand what u have to do ?

#

what does dog gate do

fierce sundial Oct 12, 2022, 3:25 PM

#

ocean yoke what does dog gate do

the dog has to find the 0s that are open doors and exit from there, like we need to do a recursion thing to help it

ocean yoke Oct 12, 2022, 3:25 PM

#

first thing how u have to solve this problem like just make it work or do it as teacher said if teacher is actually checking ur code

fierce sundial Oct 12, 2022, 3:25 PM

#

alright yeahh

fierce sundial Oct 12, 2022, 3:25 PM

#

ocean yoke then a called it again on the same list so that everything in list gets near by ...

u should send me this stuff seriously like tutorials

😭 true

#

im in 2nd year and i rlly cant grasp the concepts at al

#

its like im getting thrown shit i dont wanna learn

ocean yoke Oct 12, 2022, 3:30 PM

then u should have choosen somehting in which u fun

fierce sundial Oct 12, 2022, 3:31 PM

#

my parents would beat me up if i chose something fun

fierce sundial Oct 12, 2022, 7:46 PM

ocean yoke then u should have choosen somehting in which u fun

btw we have to declare the matrix otherwise it will be wrong

ocean yoke Oct 12, 2022, 9:05 PM
