title: Java Dictionary like from Python
body: <p>So I have been searching and searching all day, but I cannot seem to find how to create my dictionary I created in Python and create something similar in Java. I have tried looking at ArrayList and List etc. But to no avail.</p>
  
  <pre><code>PIECESDICT = {1: [[0,0], [0,1], [0,2], [1,1]], 2: [[0,0], [1,0], [0,1]], 3: [[0,0], [0,1], [1,1]], 4: [[0,0], [0,1], [1,0], [1,1]], 5: [[0,0], [1,0], [2,0]]} 
  </code></pre>
  
  <p>So here is my Dictionary, and essentially what it does is just says from coords (0,0) being the top left point of each piece. It is a piece in and of itself.</p>
  
  <p>For example Piece 1 would look like:</p>
  
  <pre><code>0
  00
  0
  </code></pre>
  
  <p>Similarly Piece 2 would look like:</p>
  
  <pre><code>00
  0
  </code></pre>
