title: 3-Dimension List or Map
body: <p>I need something like a 3-dimension (like a list or a map), which I fill with 2 Strings and an Integer within a loop. But, unfortunately I don't know which data structure to use and how.</p>
  
  <pre><code>// something like a 3-dimensional myData
  for (int i = 0; i &lt; 10; i++) {
      myData.add("abc", "def", 123);
  }
  </code></pre>
