title: Print elements from different size array
body: <pre><code>Integer [][] x = {{1,2,3},{4},{5,6}};
  </code></pre>
  
  <p>What is the best way to print the elements in stdout like this?</p>
  
  <pre><code>1
  2
  3
  4
  5
  6
  </code></pre>
  
  <p>I have tried <code>Arrays.deepToString(x) but doesnt output what I desire</code></p>
