What is the output of the following Java code?int num = 15;
While (num > 0)
Num = num - 3;
System.out.println(num) ;

A) 0
B) 3
C) 12
D) 15

The loop subtracts 3 from num in each iteration until num is no longer greater than 0. Starting from 15, it will go 12, 9, 6, 3, and finally 0, at which point the condition num > 0 is false, and it exits the loop. The last value assigned to num is 0, which is printed.
