The java.lang.Integer.longValue() method is used to return the value of this Integer as a long after a widening primitive conversion.

Syntax

public long longValue()

Parameters

No parameter is required.

Return Value

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

Exception

NA.

Example:

In the below example, the java.lang.Integer.longValue() method is used to return 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 = new Integer("25");
    Integer val2 = new Integer("-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
