General Purpose Functional Interfaces in Java 8

Java 8 introduces few general purpose functional interfaces based on the input and output to the single abstract method.

 

Most common ones are:

  1. Predicate<T> whose method

    1. takes in an argument of type T and

    2. rerturn a boolean.

  2. Consumer<T> whose method

    1. takes in an argument of type T and

    2. rerturn nothing (void).

  3. Function<T,R> whose method

Introdution to Functional Programming and Lambda Expressions

In functional programming, we think in terms of functions. While Object Oriented programming abstract over data, functional programming abstract over behavior. Instead of data, stateless functions are be passed across the code. 

Lambda expressions are Java's way of doing functional programming. Lambda expressions in computer science are anonymous functions: a function (or a subroutine) defined, and possibly called, without being bound to an identifier.

Git - Overview and Getting Started Guide

Git is a Distributes Version Control System for tracking changes in computer files and coordinating work on those files among multiple people.

It is primarily used for source code management in software development,[8] but it can be used to keep track of changes in any set of files.
