title: two IF statements vs. one AND statement
body: <p>Within java I wonder which of these is more efficient:</p>
  
  <pre><code>if(something)
     {
        if(something)
      }
  </code></pre>
  
  <p>or</p>
  
  <pre><code>if((something) &amp;&amp;(something))
  </code></pre>
  
  <p>I was wondering what the merits are for both in terms of performance. Which solutions lend themselves better to different data objects.</p>
