Java Integer byteValue() method

The byteValue() is a method of byte class under java.lang package. It converts the given number into a primitive byte type and returns the value of integer object as byte. Also, it override the byteValue() method of Number class.

Syntax

Following is the declaration of byteValue() method:

Parameter:

DataType	Parameter	Description
byte	NA	It returns the value of integer object as byte

Returns:

The byteValue() method returns the numeric value represented by this object after conversion to the primitive byte type.

Exceptions:

Compatibility Version:

Java 1.5 and above

Example 1

import java.util.Scanner;
public class IntegerByteValueExample1 {
	public static void main(String[] args) {	
		System.out.print("Enter the Desired Numeric Value: ");		
		Scanner sc = new Scanner(System.in);		
		int i = sc.nextInt();				
		sc.close();
		Integer myValue = new Integer(i);
		System.out.println("The Value of Byte is: " +myValue.byteValue());
	}
}

Output:

Enter the Desired Numeric Value: 55
The Value of Byte is: 55

Example 2

public class IntegerByteValueExample2 {
	public static void main(String[] args) {		
		Integer i = new Integer(34);		 
        // Convert Integer number to byte value
        byte b = i.byteValue();
        System.out.println(b);
	}
}

Output:

Example 3

public class IntegerByteValueExample3 {
	public static void main(String[] args) {	
		// create a Byte object b
	      Byte b = new Byte("80");
	      // convert Byte Object b to bytePrimitive
	      byte bytePrimitive = b.byteValue();	      
	      System.out.println("The Byte object is: " + b );      
	    String str = "Primitive byte value of Byte object is: "+ bytePrimitive;
	      // print byte primitive value
	      System.out.println( str );
	}
}

Output:

The Byte object is: 80
Primitive byte value of Byte object is: 80

Example 4

public class IntegerByteValueExample4 {
	public static void main(String[] args) {	
		int i = 255;
		byte b = (byte) i;
		System.out.println("b = " + b); 
		int i2 = b & 0xFF;
		System.out.println("i2 = " + i2); 
	}
}

Output:
