Supplier Interface in Java with Examples

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 in any argument but produces a value of type T. Hence this functional interface takes in only one generic namely:-

• T: denotes the type of the result

The lambda expression assigned to an object of Supplier type is used to define its

which eventually produces a value. Suppliers are useful when we don't need to supply any value and obtain a result at the same time. The Supplier interface consists of only one function:

This method does not take in any argument but produces a value of type T.

T get()

This method returns a

of type T. Below is the code to illustrate get() method:

import java.util.function.Supplier;

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

        // This function returns a random value.
        Supplier<Double> randomValue = () -> Math.random();

        // Print the random value using get()
        System.out.println(randomValue.get());
    }
}
