Question
What will be the output of the following Java program?class java { public static void main(String args[]) { int w = 5; int x = 10; first: { second: { third: { if (w == x >> 1) break second; } System.out.println(w); } System.out.println(x); } } }Options10 55 10510
Solution
The output of the given Java program will be 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 is an if condition that checks if w is equal to x right shifted by 1. The right shift operator (>>) in Java shifts all of the bits in a value to the right a specified number of times. In this case, x is 10 and if we right shift 10 by 1, we get 5 (as 10 in binary is 1010 and shifting it to the right by 1 gives 101 which is 5 in decimal).
-
Since w is indeed equal to x right shifted by 1 (as both are 5), the break statement is executed. The break statement with a label (second in this case) breaks out of the labeled block. So, the control comes out of the second block.
-
The print statement inside the second block (System.out.println(w);) is not executed because the control has already come 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 the value of x, which is 10.
-
Therefore, the output of the program is 10.
