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

Syntax

Exception

NA.

Example:

In the below example, the java.lang.Double.longValue() method is used to return a Double object after conversion to type long.

import java.lang.*;

public class MyClass {
  public static void main(String[] args) {
    
    //creating Double objects
    Double val1 = new Double("25.2");
    Double val2 = new Double("-25.2");

    //printing longValue of the Double 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
