There are many tasks in Java that aren’t covered by the core Java API. For example, if you want to parse files in the JSON data format, you won’t find tools in the libraries that you receive when you install the SDK. But the Java world is filled with open source libraries that you can download and use for free. One of these tools is called JSON.

You'll find it here on GitHub.…It's an open source library and it's completely free.…It was created by Google,…but anybody can download this code…and use it in their applications.…There are many different ways to use a Java library…and each library is responsible…for giving you the instructions.…There are tools for incorporating libraries…through something called dependencies,…but that goes beyond what we're working on in this course,…which is the core language.…Instead, I'm going to show you the simplest way…
