Play Framework makes building web applications easier with Java & Scala. It is lightweight and in a web-friendly architecture. Play is a RESTful service by default, and built targeting modern web & mobile. REST stands for REpresentational State Transfer. For a great admiration, Linkedin uses Play framework in their infrastructure. We are going to create a simple Registration & login mechanism using Play Framework to understand about it. Note that we are not going to create a database or any permanent storages, so that your registration details can be used in login only until the current run is not stopped. 1. Setting up the environment I've used the following, in developing this login form Java Development Kit 1.8.0_121 ( http://www.oracle.com/technet work/java/javase/downloads/ index-jsp-138363.html ) IntelliJ IDEA 2016.3.3 ( https://www.jetbrains.com/ide a/#chooseYourEdition ) Scala plugin 2.12.1 installed ( https://www.scala-lang.org/download/ )

Even if the requirement is just a minor change, improper coding style might lead you to several changes that occur like a chain.  Sometimes you might have to create the logic, whereas another person (or a team) is working on the UI. You will not know how will the UI look like until it is final
