The longValue() method of Double class is a built in method to return the value specified by the calling object as long after type casting.
Syntax
DoubleObject.longValue()
Parameters : It takes no parameters.
Return type : It returns an long value i.e. the type casted value of the DoubleObject.
Below is the implementation of the above method.
Code 1 :
// Java Code to implement // longValue() method of Double classclass GFG {    // Driver method    public static void main(String[] args)    {          // creating a Double object        Double d = new Double(1022);          // longValue() method of Double class        // typecast the value        long output = d.longValue();          // printing the output        System.out.println(output);    }} |
Output
1022
Code 2 :
// Java Code to implement // longValue() method of Double classclass GFG {    // Driver method    public static void main(String[] args)    {          // creating a Double object        Double d = new Double(-1023.23);          // longValue() method of Double class        // typecast the value        long output = d.longValue();          // printing the output        System.out.println(output);    }} |
Output
-1023
