Following is the declaration of longValue() method:

Parameter:

DataType	Parameter	Description
NA	NA	This method does not accepts any parameter.

Returns:

The longValue() method returns the numeric value represented by this object after conversion to type long.

Exceptions:

Compatibility Version:

Java 1.2 and above

Example 1

  public class IntegerLongValuetExample1 {  public static void main(String[] args) {      long x = 6666;      long y = 55;      Long i = new Long(x);      Long result = i.longValue()/y;      System.out.println(“Value is = “+result);          }  }  

Test it Now

Output:

Value is = 121

Example 2

  import java.util.Scanner;  public class IntegerLongValuetExample2 {  public static void main(String[] args) {  // input number from console  System.out.print(“Enter The Desired Integer Value: “);  Scanner readInput = new Scanner(System.in);  int i = readInput.nextInt();  readInput.close();  Integer myValue = new Integer(i);  System.out.println(“Long Value is: ” + myValue.longValue());          }  }  

Output:

Enter The Desired Integer Value: 58648  Long Value is: 58648

Example 3

  public class IntegerLongValuetExample3 {  public static void main(String[] args) {        Long object1 = new Long(298689);         // returns the value of this Long object as a long        long l1 = object1.longValue();        System.out.println(“Value of l1 as long is: ” + l1);                Long object2 = new Long(-98723886);                // It will return the value of this Long as a long        long l2 = object2.longValue();        System.out.println(“The Value of l2 as long is: ” + l2);          }  }  

Test it Now

Output:

Value of l1 as long is: 298689  The Value of l2 as long is: -98723886
