Java OCA OCP Practice Question 353

Question

What will the following program print? 

public class Main{ 
    public static void main (String args [])  { 
        int counter = 0; 
        outer: //from ww  w .  jav a 2  s . c om
        for  (int i = 0; i < 3; i++)  { 
            middle: 
            for  (int j = 0; j < 3; j++)  { 
                inner: 
                for  (int k = 0; k < 3; k++)  { 
                    if  (k - j > 0)  { 
                        break middle; 
                     } 
                    counter++; 
                 } 
             } 
         } 
        System .out.println (counter); 
     } 
}

Select 1 option

  • A. 2
  • B. 3
  • C. 6
  • D. 7
  • E. 9 


Correct Option is  : B

Note

The key is that the middle loop is broken as soon as k-j becomes > 0.

This happens on every second iteration of inner loop when k is 1 and j is 0.

When middle is broken inner cannot continue.

So the next iteration of outer starts.
