Java Integer byteValue() Method

Java byteValue() method belongs to the Integer class of the java.lang package and overrides the byteValue() method of the Number class. This method returns the byte equivalent of the Integer object after a narrowing primitive conversion(Conversion of higher data type into lower data type).

In short, this method is used to convert an Integer object into a byte value.

Syntax:

public byte byteValue()  

Parameter:

No parameter is passed in this method.

Returns:

The numerical equivalent of the object of a byte type is created after conversion.

Example 1:

Here, using the byteValue() function the integer values are converted into its numerical byte equivalent.

import java.lang.Integer;

public class StudyTonight
{  
    public static void main(String[] args) 
      {  
        //converting integer object into byte
          Integer x = 95;
          byte i=x.byteValue();
          System.out.println(" Equivalent byte value is " +i);
          
          
          Integer y = -25;  
          byte d = y.byteValue();  
          System.out.println(" Equivalent byte value is " +d);
      }  
}

Equivalent byte value is 95
Equivalent byte value is -25

Example 2:

Here is a user-defined example where anyone using this code can put a value of his choice and get the equivalent byte value.

import java.util.Scanner;  
public class StudyTonight
{  
    public static void main(String[] args) 
    {  
         try
           {
              System.out.print("Enter the value to be converted : ");  
              Scanner sc = new Scanner(System.in);  
              int i = sc.nextInt();  
              Integer n = i ;  
              byte val = n.byteValue();  
              System.out.println("Byte Value is: " + val);  
           }
         catch(Exception e)
           {
              System.out.println("not a valid integer"); 
           }
    }
}

Enter the value to be converted : 67
Byte Value is: 67
****************************************
Enter the value to be converted : -93
Byte Value is: -93
