Solution
The correct answer is 10.
Here's the step-by-step explanation:
-
The program starts with the declaration of two integer variables, w and x, with values 5 and 10 respectively.
-
Then, there are three labeled blocks: first, second, and third.
-
Inside the third block, there's an if statement that checks if w is equal to x shifted right by 1. The right shift operator (>>) in Java shifts the bits of the number to the right and fills 0 on voids left as a result. The right shift by 1 of x (which is 10 in binary form 1010) results in 5 (in binary form 101). So, the condition w == x >> 1 is true.
-
When the condition is true, the break statement is executed. The break statement with a label (in this case, second) breaks the labeled block. So, the control goes out of the second block.
-
The statement System.out.println(w); inside the second block is not executed because the control has already moved out of the second block due to the break statement.
-
The next statement is System.out.println(x); which is outside the second block. So, it is executed and prints 10.
-
Therefore, the output of the program is 10.
