Java - Byte intValue() method

---

---

Description

The Java Byte intValue() returns the value of this Byte as a int.

Declaration

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

public int intValue()

Specified by

intValue in class Number

Parameters

NA

Return Value

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

Exception

NA

Example 1

The following example shows the usage of Byte intValue() 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 int variable is created and assigned a int value using intValue() 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 int primitive d
      int d;

      // assign primitive value of b to d
      d = b.intValue();

      String str = "Primitive int value of Byte object " + b + " is " + d;

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

Output

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

Primitive int value of Byte object 100 is 100

Example 2

The following example shows the usage of Byte intValue() 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 int variable is created and assigned a int value using intValue() 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 int primitive d
      int d;

      // assign primitive value of b to d
      d = b.intValue();

      String str = "Primitive int value of Byte object " + b + " is " + d;

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

Output

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

Primitive int value of Byte object 100 is 100

Example 3

The following example shows the usage of Byte intValue() 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 int variable is created and assigned a int value using intValue() 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 int primitive d
      int d;

      // assign primitive value of b to d
      d = b.intValue();

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

      // print d 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
