java.lang.Byte intValue()


The intValue() method of Byte class returns the value of this Byte as an int after a widening primitive conversion.

Important Notes:

  • The method intValue() is specified by intValue in class Number.

Method Syntax

public int intValue()

Method Argument

Data Type Parameter Description

Method Returns

The intValue() method of Byte class returns the numeric value represented by this object after conversion to type int.


Requires Java 1.1 and up

Java Byte intValue() Example

Below is a simple java example on the usage of intValue() method of Byte class.


import java.util.Scanner;

 * This example source code demonstrates the use of 
 * intValue() method of Byte class.

public class ByteIntValueExample {

	public static void main(String[] args) {

		 * Editor's Note
		 * Be extra careful in using this method
		 * as it uses widening concept
		// ask for user input
		System.out.print("Enter a number:");

		// read the user input
		Scanner s = new Scanner(;
		String value = s.nextLine();
		Byte byteValue = new Byte(value);
		// convert byteValue into int
		int result = byteValue.intValue();
		System.out.println("int value is "+result);



Basically on the above example, we have asked the user to enter a number on the console. Internally the input value is assign to a Byte object. We then use the intValue() method to convert it into type int. It doesn’t do much however it shows the basic behaviour of this method.
