title: Why int[] a = new int[1] instead of just int a?
body: <p>Is there some hidden meaning in this code which I don't see in java? How can it be useful?</p>
  
  <pre><code>int[] a = new int[1];
  </code></pre>
  
  <p>than just</p>
  
  <pre><code>int a;
  </code></pre>
  
  <p>because from my point of view it's the same?</p>
