title: Java JSON Array Text Files
body: <p>I've seen to hit a bump with this. I can't seem to get the array of the map from text file. I mean, I can get everything else BUT the map's array tiles.</p>
  
  <p>This is the text file:</p>
  
  <pre><code>{
  'name': 'map_one.txt',
  'title': 'xxx One',
  'currentMap': 4,
  'rightMap': 3,
  'lefttMap': 5,
  'downMap': 1,
  'upMap': 2,
  'items': [
      { name: 'Pickaxe', x: 5, y: 1 },
      { name: 'Battleaxe', x: 2, y: 3 }
  ],
      'map': [ [ 1,3,1,1,1,24,1,1,1,1,1,1,1 ],
      [ 1,3,1,1,1,24,1,1,1,1,1,1,1 ],
      [ 1,7,1,1,1,24,1,1,24,1,1,1,1 ],
      [ 1,7,1,1,7,1,1,1,24,1,1,1,1 ],
      [ 1,7,7,7,1,24,24,24,24,1,1,1,1 ],
      [ 1,1,7,1,1,24,1,24,1,1,1,1,1 ],
      [ 1,1,1,1,1,24,1,1,1,1,1,1,1 ],
      [ 1,1,3,1,1,24,1,1,1,1,1,1,1 ],
      [ 1,3,3,1,1,24,1,1,1,1,1,1,1 ]]
  };
  </code></pre>
  
  <p>and when I run it, I get this:</p>
  
  <pre><code>==========================
   JSON MAP LOAD...
  ==========================
  
  Name of map: xxx One
  File of map: map_one.txt
  ID of map: 4
  
  ==========================
   ITEMS IN MAP
  ==========================
  
  # OF ITEMS: 2
  
  &gt;&gt; Name: Pickaxe (5, 1)
  &gt;&gt; Name: Battleaxe (2, 3)
  
  ==========================
   TILES OF MAP
  ==========================
  
  null
  Press any key to continue . . .

  <p>See the null? It's *suppose to be numbers of arrays.</p>
