Java: Arithmetic operation on byte

Question

What happened to my code? The following code worked for integer type of data, but couldn\'t work for byte type of data.

public class Exchange {
    public st         


        

Answer 1

Corrected code is here

 public static void main(String[] args) {
    //int a = 23, b = 44;
    byte a = 23, b = 44;
    a = (byte) (a + b);
    b = (byte) (a - b);
    a = (byte) (a - b);
    System.out.println("a=" + a + "b=" + b);
}
