What is Apply function in Java?

The identity function in math is one in which the output of the function is equal to its input. In Java, Function is a functional interface whose identity method returns a Function that always returns its input arguments .

util. function package which has been introduced since Java 8, to implement functional programming in Java . It represents a function which takes in one argument and produces a result.8 Ara 2021

Interface Function<T,R> Type Parameters: T – the type of the input to the function R – the type of the result of the function All Known Subinterfaces : UnaryOperator<T> Functional Interface: This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

Interface Function<T,R> Type Parameters: T – the type of the input to the function R – the type of the result of the function All Known Subinterfaces : UnaryOperator<T> Functional Interface: This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

A functional interface can have any number of default methods. Runnable, ActionListener, Comparable are some of the examples of functional interfaces. Functional Interface is additionally recognized as Single Abstract Method Interfaces. In short, they are also known as SAM interfaces.
