Java - Byte byteValue() method

---

---

Description

The Java Byte byteValue() returns the value of this Byte as a byte.

Declaration

Following is the declaration for java.lang.Byte.byteValue() method

public byte byteValue()

Overrides

byteValue in class Number

Parameters

NA

Return Value

This method returns the numeric value represented by this object after conversion to type byte.

Exception

NA

Example 1

The following example shows the usage of Byte byteValue() method with Byte object created using new operator. We're creating a Byte variable and assigned it an Byte object created using new operator. Then a byte variable is created and assigned a byte value using byteValue() method and then result is printed.

package com.tutorialspoint;
public class ByteDemo {
   public static void main(String[] args) {

      // create a Byte object b
      Byte b;

      // assign value to b
      b = new Byte("100");

      // create a byte primitive bt
      byte bt;

      // assign primitive value of b to bt
      bt = b.byteValue();

      String str = "Primitive byte value of Byte object " + b + " is " + bt;

      // print bt value
      System.out.println( str );
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Primitive byte value of Byte object 100 is 100

Example 2

The following example shows the usage of Byte byteValue() method with Byte object created using valueOf(String) method. We're creating a Byte variable and assigned it an Byte object created using valueOf(String) method. Then a byte variable is created and assigned a byte value using byteValue() method and then result is printed.

package com.tutorialspoint;
public class ByteDemo {
   public static void main(String[] args) {

      // create a Byte object b
      Byte b;

      // assign value to b
      b = Byte.valueOf("100");

      // create a byte primitive bt
      byte bt;

      // assign primitive value of b to bt
      bt = b.byteValue();

      String str = "Primitive byte value of Byte object " + b + " is " + bt;

      // print bt value
      System.out.println( str );
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Primitive byte value of Byte object 100 is 100

Example 3

The following example shows the usage of Byte byteValue() method with Byte object created using valueOf(byte) method. We're creating a Byte variable and assigned it an Byte object created using valueOf(byte) method. Then a byte variable is created and assigned a byte value using byteValue() method and then result is printed.

package com.tutorialspoint;
public class ByteDemo {
   public static void main(String[] args) {

      // create a Byte object b
      Byte b;

      // assign value to b
      b = Byte.valueOf((byte) 100);

      // create a byte primitive bt
      byte bt;

      // assign primitive value of b to bt
      bt = b.byteValue();

      String str = "Primitive byte value of Byte object " + b + " is " + bt;

      // print bt value
      System.out.println( str );
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Primitive byte value of Byte object 100 is 100
