Question

How does Java convert integer value into byte

Answer 1

When an integer value is converted into a byte, Java cuts-off the left-most 24 bits.

We will be using bitwise AND to mask all of the extraneous sign bits.

Here is an illustration of a Java Program that converts an integer to byte.

import java.util.Scanner;

public class Integer_Conversion

{

   public static void main(String[] args)

    {

        int a;

        byte b;

        Scanner s = new Scanner(System.in);

        System.out.print("Enter any integer:");

        a = s.nextInt();

        b = (byte) a; 

        System.out.println("Conversion into byte:"+b);

    }

}

Output:

Enter any integer: 100

Conversion into byte:100
