Question

I try do disply a 2 D table but for some reason I can’t, I don’t see what i wrote wrong.

This is my code (I am working in vim):

            int [][] tab = new int [5][5];

            for (int i= 0; i<tab.length ; i++){
                    for (int j =0; j<tab[i].length; j++){
                            tab[j][i]=i;
                            System.out.println("" + tab[j][i]);
                    }
                    System.out.println("");
            }
    }

The result of this code is:

0

In the inner loop, replace: –

System.out.println("" + tab[j][i]);

with: –

System.out.print(" " + tab[j][i]);

since you want to continue printing in the same row.
