title: Insert int Array to ArrayList
body: <p>Can I insert array to array and read it afterwards in Java? Something like this:</p>
  
  <pre><code>ArrayList&lt;Integer&gt; array = new ArrayList&lt;&gt;();
  array.add([1,4,5]);
  array.add([3,7,2]);
  </code></pre>
  
  <p>Array: </p>
  
  <pre><code>{ [1,4,5], [3,7,2] }
  </code></pre>
  
  <p>And read like:</p>
  
  <pre><code>print(array[0][1]); //prints 4 
  </code></pre>
  
  <p>Thanks.</p>
