The byteValue() method of Integer class of java.lang package converts the given Integer into a byte after a narrowing primitive conversion and returns it (value of integer object as a byte). Also, remember this method does override byteValue() method of the Number class.  

The package view is as follows:

--> java.lang Package 
    --> Integer Class
        --> byteValue() Method

Syntax :

public byte byteValue()

Return Type: Returns the numeric value represented by this object after conversion to byte type.

Note: It is compatible with Java 1.5 and onwards.

Example 1:

Java 
// Java program to Illustrate byteValue() Method
// Of Integer Class 

// Importing required class
import java.lang.Integer;

// Main Class
class GFG {

    // Main driver method
    public static void main(String args[]) {

        // Creating an Integer object and
        // passing custom integer input
        Integer a = new Integer(34);

        // Converting integer number to byte value
        // using byteValue() method
        byte b = a.byteValue();

        // Printing the corresponding byte value
        System.out.println(b);
    }
}
Output:
34

Example 2:

Java 
// Java Program to Illustrate byteValue() Method
// of Integer Class

// Importing required classes
import java.lang.*;
import java.util.*;

// Main Class
class GFG {

    // Main driver method
    public static void main(String[] args)
    {

        // Creating a Byte object
        Byte b = new Byte("01");

        // Converting Byte to byte primitive
        // using byteValue() method
        Byte bp = b.byteValue();

        // Display statement
        System.out.println("Byte object : " + b);

        // Primitive byte value of custom Byte passed above
        String str
            = "Primitive byte value of Byte object : " + bp;

        // Printing byte primitive value
        System.out.println(str);
    }
}
Output:
Byte object : 1
Primitive byte value of Byte object : 1
