The All-in-One Guide to Java Programming


**Play** is a web-framework for building scalable, asynchronous web-applications using the Akka
concurrency model. Play 2 can work with either Scala or Java, although we’re going to assume
you’re using Scala for now.

# Quick overview of play
After installing Play, you can create a new app by running the following on the command line:
```
$ play new
```
Play applications have a very specific project structure as follows:
* **App:**  Source code of your application
  * Controllers - Controllers that define Actions.
  * Views - Scala-based view templates that produce HTML (by default).
* **Conf:** Configuration files and data, such as routes.
* **Project:** Project build scripts
* Public: Publicly accessible static files.
  * Images - Images used by your web application.
  * Javascript - Javascript files
  * Stylesheets - CSS files

Play includes all of the pieces necessary to build a web application, including an HTTP server, so
you don’t need to run your application inside a container. You can start your application at any time
by typing:

```
$ play run
```
