Java OCA OCP Practice Question 861

Question

What is the output of the following code snippet? 

3: int count = 0; 
4: V: for(int row = 1; row <=3; row++) 
5:   for(int col = 1; col <=2 ; col++) { 
6:     if(row * col % 2 == 0) continue V; 
7:     count++; 
8:   } 
9: System.out.println(count);
  • A. 1
  • B. 2
  • C. 3
  • D. 4
  • E. 6
  • F. The code will not compile because of line 6. 


A.

Note

The expression on line 5 is true when row * col is an even number.

On the first iteration, row = 1 and col = 1, so the expression on line 6 is false, the continue is skipped, and count is incremented to 1.

On the second iteration, row = 1 and col = 2, so the expression on line 6 is true and the continue ends the outer loop with count still at 1.

On the third iteration, row = 2 and col = 1, so the expression on line 6 is true and the continue ends the outer loop with count still at 1.

On the fourth iteration, row = 3 and col = 1, so the expression on line 6 is false, the continue is skipped, and count is incremented to 2.

Finally, on the fifth and final iteration, row = 3 and col = 2, so the expression on line 6 is true and the continue ends the outer loop with count still at 2.

The result of 2 is displayed, so the answer is option B.
