Loop diagonally through two dimensional array

Question

I wrote the following code to walk half the diagonals of an array:

String[][] b = [a,b,c]
               [d,e,f]
               [g,h,i];  

public void LoopD         


        

Answer 1

Here is the code:

public void loopDiag(String [][] b) {

        boolean isPrinted  = false;
        for (int i = 0 ; i < b.length ; i++) {
            String temp="";
            int x=i;
            for(int j = 0 ; j < b.length ; j++) {
                int y = j;
                while (x >= 0 && y < b.length) {
                    isPrinted = false;
                    temp+=b[x--][y++];                  
                }
                if(!isPrinted) {
                    System.out.println(temp);
                    isPrinted = true;
                }
            }
        }
    }
