title: Implementation of A Star (A*) Algorithm in Java
body: <p>Disclaimer: I have little background in Java, since I am predominantly a C# developer.</p>
  
  <p>Would like to have the java implementation of A* algorithm.<br>
  Yes, I saw many versions of the same online and I am unable to choose between them.  </p>
  
  <p>I am looking for an A* algorithm implementation that uses all new features of java that makes the algorithm faster(even if a tad bit). The reason is that we are implementing that for path-finding on an <a href="http://en.wikipedia.org/wiki/Massively_multiplayer_online_game"><code>MMO</code></a> and so, performance is the top priority.  </p>
  
  <p>Any pointers ( on atleast where to look ) ?</p>
