Java BiFunction Example

BiFunction is a functional interface which represents a function that accepts two arguments and produces a result. This is the two-arity specialization of Function.

Java BiFunction Example

Create a Person class:
public class Person { private String name; private int age; public Person(String name, int age) { super(); this.name = name; this.age = age; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
Here is an example of a BiFunction interface:

public class BiFunctionExample { public static void main(String[] args) { BiFunction<Person, Person, Integer> biFunction = (p1,p2) -> { return p1.getAge() + p2.getAge(); }; int totalAge = biFunction.apply(new Person("Ramesh", 10), new Person("ram", 10)); System.out.println(totalAge); } }
