The LongSupplier Interface is a part of the java.util.function package which has been introduced since Java 8, to implement functional programming in Java. It represents a function which does not take in any argument but produces a long value.

The lambda expression assigned to an object of LongSupplier type is used to define its getAsLong() which eventually applies the given operation on its argument. It is similar to using an object of type Supplier<Long>

Functions in LongSupplier Interface

The LongSupplier interface consists of the only one function:

1. getAsLong()

This method does not take in any value but produces a long-valued result.


long getAsLong()

Return Value: This method returns a long value.

Below is the code to illustrate getAsLong() method:


// Java program to illustrate
// getAsLong() method
import java.util.function.LongSupplier;
public class GFG {
    public static void main(String args[])
        // Create a LongSupplier instance
            = () -> (int)(Math.random() * 10);
        // Get the long value
        // Using getAsLong() method
