title: Java wrapper around Map-like implementation
body: <p>I am looking for a stable and easy-to-use implementation of a wrapper around Java's Map interface. Basically, I'd like the functionality of Android's <a href="http://developer.android.com/reference/android/os/Bundle.html" rel="nofollow" title="Bundle">Bundle</a> class so I can do this:</p>
  
  <p><code>float  getFloat(String key, float defaultValue)</code><br>
  <code>void   putShort(String key, short value)</code><br>
  <code>String     getString(String key, String defaultValue)</code><br>
  <code>void   putInt(String key, int value)</code></p>
  
  <p>and so on. I've seen <a href="http://docs.oracle.com/javase/7/docs/api/java/util/ResourceBundle.html" rel="nofollow" title="ResourceBundle">ResourceBundle</a> class, but I'd like more than <code>getObject</code> and <code>getString</code> methods.</p>
  
  <p>Are there any other alternatives?</p>
