IntSupplier Interface is a part of the java.util.function package which is introduced in Java 8. It is an in-built Functional Interface. This function doesn’t expect any input but produces a int-valued output. In this post, we are going to see several implementations of IntSupplier Interface by using different examples.

Look at IntSupplier Javadoc description below:
As you’ve seen in the above screenshot, IntSupplier Interface contains only the following function:
int getAsInt();
This method represents a supplier of int-valued results. This is the
int-producing primitive specialization of Supplier.
Example:
import java.util.function.IntSupplier;
public class IntSupplierInterfaceJava8Example1 {
public static void main(String[] args) {
System.out.println("IntSupplier Interface - Example");
int x = 10;
int y = 50;
IntSupplier intSupplierObj = () - > x * y;
System.out.println("Result: " + intSupplierObj.getAsInt());
}
}
Java 8 IntSupplier Interface is an absolute useful addition as part of ‘Functional Interfaces’ and can serve variety of purposes. It is quite powerful as it can be used as a higher order functions through lambda functions and above examples could help you to get better idea on how to implement it.
