can't find the logic

hy all, i can't figure out the logic of this

The position of A and B is random. And A and B is linked by *. What is the logic of this?? do i have to make an array 10 x 10, and access the index randomly to put A??? or what??

what is the actual assignment, find the A and B positions and putting *'s? If so first of all find exact location of 'A' and 'B', then put the star's.

The assignment is to place A and B randomly, and connect it with *. So, whenever the program is run, the position of A and B is change and linked with *.

Pencil and paper. That’s what you need. Write down an explanation of how you would do that. Once you have got it into very simple words (pseudo-code), it will be easy to convert to code.

The solution is pretty easy ;)

1. Fill A's row till B's column
2. Fill B's column till A's row

i have found the way to place A and B randomly. Here is my scrip

import java.util.Random;

public class OrderMap {
    public static void main(String args[]){
        
        int Y=10;
        int X=10;
        
        OrderMap baru = new OrderMap();
        
        int y = baru.ran();
        int x = baru.ran();
        for(int i=0; i<Y; i++){
            for(int j=0; j<=X; j++){
                if(y==x){
                    x=x+1;
                }
                System.out.print("|");
                if(i==y && j==x){
                    System.out.print("A");
                }
                else if(i==x && j==y){
                    System.out.print("B");
                }
                else if(y>x){
                    if(i==x && j==x){
                        System.out.print("*");
                    }
                    else{
                        System.out.print(" ");
                    }
                }
                else if(y<x){
                    if(i==x && j==x){
                        System.out.print("*");
                    }
                    else{
                        System.out.print(" ");
                    }
                }
            }
            System.out.println("");
        } 
        System.out.println(y + " " + x);
    }
    
    private int rand;
    
    public int ran(){
        int nilai[]= new int[10];
        
        Random create = new Random();
        rand = create.nextInt(nilai.length);
        return rand;
    }
}

but still, i can conect A and B with *. Is there any suggestion???

Same suggestion you've already received:

My suggestion is to scrap what you have done, turn off the computer, and follow Campbell's suggestion of solving the problem with pencil and paper. If you really do this, then writing the code will be simple. Well, okay I have a second suggestion: use the power of objects!
