Java program converts UNSIGNED byte to JAVA type

First, let's declare the byte value.

byte val1　=　127;
byte val2　=　-128;

To convert the unsigned byte given above, you can use the following. Here, we first declare the variable "val1" implement it.

(int) val1　& 0xFF

Now it's the second variable "val2"

(int) val2　& 0xFF

Let's see a complete example, converting UNSIGNED byte to JAVA type.

Example

import java.util.*;
public class Demo {
　　　public static void main(String[] args) {
　　　　　　byte val1　=　127;
　　　　　　byte val2　=　-128;
　　　　　　System.out.println(val1);
　　　　　　System.out.println((int) val1　& 0xFF);
　　　　　　System.out.println(val2);
　　　　　　System.out.println((int) val2　& 0xFF);
　　　}
}

Output Result

127
127
-128
128
