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


public long longValue()


No parameter is required.

Return Value

Returns the double value represented by this object converted to type long.




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
