title: How can I discover which classes implement methods of a class using Eclipse?
body: <p>I'm working with Eclipse and 2 API. Is there any way I can get information about which classes use a method of a class? For example, I have <code>gameStarted()</code> method in Game class, I would like to know other classes who use <code>gameStarted()</code> method. I also want to know which classes extend a class and which classes create an instance of a class.</p>
  
  <p>I think I need to know this in order to understand how a part of an API works.</p>
