what are Static Nested Classes in Java? <p>I am new to java and have been scratching my head understanding some its concepts. I am following the tutorial <a href="http://docs.oracle.com/javase/tutorial/java/javaOO/nested.html" rel="nofollow">Java tutorial</a>. However, I cannot find the usefulness of using Static Nested Classes. I mean I think I need some good examples as to why I should want to use it. Can someone provided me some codes as examples so I can understand it better? thax</p>
