IntBinaryOperator 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 expects two arguments of type int as an input and produces a int type result. As it is a functional interface, it can be used assignment target for lambda expression or method reference. In this post, we are going to see several implementations of IntBinaryOperator Interface by using different examples.

Look at IntBinaryOperator Javadoc description below:
IntBinaryOperator Interface contains below method:
applyAsInt
Let’s discuss this method:
applyAsInt
This method performs operation on the given arguments and return the int-valued result.
int applyAsInt(int left, int right);
Lets understand above mentioned method through below example:
Example. ‘applyAsInt’ method
import java.util.function.IntBinaryOperator;
public class IntBinaryOperatorInterfaceJava8Example {
public static void main(String[] args) {
System.out.println("IntBinaryOperator Interface - 'applyAsInt' example \n");
//1. Annonymous Implementation
IntBinaryOperator annonymousObj = new IntBinaryOperator() {
@Override
public int applyAsInt(int x, int y) {
return x + y;
}
};
//2. Lambda Implementation
IntBinaryOperator lambdaObj = (x, y) -> x + y;
//1
System.out.println("Result : " + annonymousObj.applyAsInt(5, 6));
//2
System.out.println("Result : " + lambdaObj.applyAsInt(5, 6));
}
}
Output:
IntBinaryOperator Interface - 'applyAsInt' example Result : 11 Result : 11
Java 8 IntBinaryOperator 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.
