Last Updated : 11 Jul, 2025

The

is a part of the

package which has been introduced since Java 8, to implement

in Java. It represents a function which does not take any argument but produces an int value. The lambda expression assigned to an object of IntSupplier type is used to define its

which eventually applies the given operation on its argument. It is similar to using an object of type

<Integer>

The IntSupplier interface consists of the only one function:

This method does not take in any value but produces an int-valued result.

int getAsInt()

This method returns

. Below is the code to illustrate getAsInt() method:

// Java program to illustrate
// getAsInt method of IntSupplier Interface

import java.util.function.IntSupplier;

public class GFG {
    public static void main(String args[])
    {

        // Create a IntSupplier instance
        IntSupplier
            sup
            = () -> (int)(Math.random() * 10);

        // Get the int value
        // Using getAsInt() method
        System.out.println(sup.getAsInt());
    }
}
