Convert byte to equivalent hexadecimal in Java

To convert a byte to its equivalent hexadecimal, use the toHexString() method in Java.

First, let's take a byte value.

byte val1　= (byte)90;

Before using this method, let's do more operations. Now mask the byte value:

int res = val1　& 0xFF;

Now let's see the complete example and use the toHexString() method to convert the byte to its equivalent hexadecimal.

Example

public class Demo {
　　　public static void main(String[] args) {
　　　　　　byte val1　= (byte)90;
　　　　　　System.out.println("Byte = ",+val1);
　　　　　　int res = val1　& 0xFF;
　　　　　　System.out.println("Hexadecimal = ",+Integer.toHexString(res));
　　　}
}

Output Result

Byte =　90
Hexadecimal =　5a
