It has been specifically designed to have as few [implementation dependencies](http://www.java-tips.org/other-api-tips-100035/60-netbeans/1025-what-is-an-implementation-dependency-and-whathowwhen-should-i-use-one.html) as possible. Java applications are typically compiled to [bytecode](https://en.wikipedia.org/wiki/Bytecode) that can run on any [Java virtual machine](https://en.wikipedia.org/wiki/Java_virtual_machine) (JVM) regardless of computer architecture.

- JAVA IS EVERYWHERE. It is one of the most sought after programming languages. It is a standard for enterprise software, web-based content, games and mobile apps, as well as the [Android operating system](https://developer.android.com/index.html).

- [Write once, run anywhere](https://en.wikipedia.org/wiki/Write_once,_run_anywhere) policy: Programs written in Java are compiled into machine-independent bytecodes, so it can run on any Java platform. Basically, Java is [Platform Independent](https://en.wikipedia.org/wiki/Cross-platform#Platform-independent_software)

Java has built-in [application programming interfaces](https://en.wikipedia.org/wiki/Application_programming_interface) (APIs) for I/O, networking, data structures, concurrency, and many other functions. Standard libraries can be supplemented by open source libraries like Apache Commons, Google Guava, Netty and others.

If you need to write a web/enterprise app, or you need data persistence or you need to do cryptography, no problem! Java is all you require. There are many standard tools/practices that extend the Java ecosystem, thanks to the [Java Community Process](https://www.jcp.org/en/introduction/overview) (JCP)!
