What will be printed as a result of the following code execution?


public class Main {
    public static void main(String args[]) {
        byte b = 0;
        while (++b > 0);
        System.out.println(b);
    }
}

Program will enter an infinite loop
-128
0
127

Explanation

Variables of byte type store values in the range -128 .. 127. When the value of a b variable reaches the maximum value allowed for this type (127) in the loop, the following increment (++) will reset it to a minimum allowed value (-128). It will start the countdown all over again.
