What will be output of following program? public class Test{public static void main(String[] args){byte b=127; b++; b++; System.out.println(b); } } ?
Correct answer: B. -127
- A. 127
- B. -127
- C. 129
- D. -129
Explanation
A byte can hold values from -128 to 127, so incrementing 127 wraps to -128 and the second increment produces -127. Java byte arithmetic therefore gives -127 rather than 129.
