A good place to study Thread, Runnable and other thread composing code.

Hello, I am looking for a good tutorial about threads and runnables. I want to understand how to use threads and synchronized keyword to provide a usable multithreaded code, but I am beginner to intermediate in Java so I want an adequate tutorual about these. Also a book suggestion would be nice.
