Welcome to my introduction to [Java 8](https://jdk8.java.net/). This tutorial guides you step by step through all new language features. Backed by short and simple code samples you'll learn how to use default interface methods, lambda expressions, method references and repeatable annotations. At the end of the article you'll be familiar with the most recent [API](http://download.java.net/jdk8/docs/api/) changes like streams, functional interfaces, map extensions and the new Date API. No walls of text - just a bunch of commented code snippets. Enjoy!

As you can see both code snippets are almost identical but the parallel sort is roughly 50% faster. All you have to do is change `stream()` to `parallelStream()`.

As already mentioned maps don't support streams. Instead maps now support various new and useful methods for doing common tasks.
