title: create a 2 dimensional array of HashMaps in java
body: <p>I would like to create a 3 dimensional array in java where the first two dimensions are indices (0-100) and (0-4) and the 3rd dimension is a dictionary index (12, 18, 22, 49, etc)</p>
  
  <p>How can I set this up?  I thought: </p>
  
  <pre><code>    HashMap&lt;Integer, Integer&gt;[][] mem;
      mem = new HashMap&lt;Integer, Integer&gt;[101][5];
  </code></pre>
  
  <p>But I am getting errors.  Am I approaching this correctly?</p>
  
  <p>Thanks!</p>
