Java Integer - longValue() Method

public long longValue()


No parameter is required.

Return Value

Returns the numeric value represented by this object after conversion to type long.




In the example below, the java.lang.Integer.longValue() method returns a Integer object after conversion to type long.

import java.lang.*;

public class MyClass {
  public static void main(String[] args) {
    //creating Integer objects
    Integer val1 = 25;
    Integer val2 = -25;

    //printing longValue of the Integer objects
    System.out.println("longValue of the val1 is: " + val1.longValue()); 
    System.out.println("longValue of the val2 is: " + val2.longValue());   

The output of the above code will be:

longValue of the val1 is: 25
longValue of the val2 is: -25
