class LabeledBreakOut
{
    public static void main(String[] args) 
    {
        int[][] squareMatrix = {{4, 3, 5}, {2, 1, 6}, {9, 7, 8}};
        int sum = 0;
outer:                            // label
        for (int i = 0; i < squareMatrix.length; ++i)
        {          // (1)
            for (int j = 0; j < squareMatrix[i].length; ++j) 
            {  // (2)
                if (j == i) break;        // (3) Terminate this loop.                                          //     Control to (5).
                System.out.println("Element[" + i + ", " + j + "]:" +
                       squareMatrix[i][j]);
                sum += squareMatrix[i][j];
                if (sum > 10) 
                    break outer;// (4) Terminate both loops.
                                //     Control to (6).
            } // end inner loop
          // (5) Continue with outer loop.
        } // end outer loop
        // (6) Continue here.
        System.out.println("sum: " + sum);
    }
}
 

The answer is Element[1, 0]: 2
Element[2, 0]: 9
sum: 11


The question is why is [2,1] [1,2 ]is not calculated ???
please help me

Initially when I=0 and j=0 if(j==i) break; is executed and so control breaks out of the inner loop.
In the next iteration of the outter loop, we have
i=1 and j=0, this time the first if will not get exeuted and control proceeds to execute the System.out.println()

Output at this point is
Element[1, 0]: 2

And the value of sum is 2, which is less than 10, so second if is not executed

Now moving to next iteration of outter loop
i=2 and j=0, this time also the first if will not get exeuted and control proceeds to execute the System.out.println()

Output at this point is
Element[2, 0]: 9

Now sum is 9+2 =11 greater than 10, so the second if gets executed and comes out of the scope defined by the label outer:

Hope this helps :-)
