How can I see how a specific algorithm in Java is implemented? For example, the Arrays.sort() method sorts different types of arrays. However, I'm unable to understand what goes on under the hood. How do I see how this method is implemented?

    The source codes are contained in src.zip that comes with the JDK. – Kayaman Nov 22 '14 at 22:08

You can download java sources from the official site.

And for non-open java libraries you can use decompiler.
