title: Static Classes In Java
body: <p>Is there anything like <code>static class</code> in java?</p>
  
  <p>What is the meaning of such a class. Do all the methods of the static class need to be <code>static</code> too?</p>
  
  <p>Is it required the other way round, that if a class contains all the static methods, shall the class be static too?</p>
  
  <p>What are static classes good  for?</p>
