title: Is ++x more efficient than x++ in Java?
body: <p>During a programming class, the professor was teaching us about <code>x++</code> and <code>++x</code>, with x being an integer.</p>
  
  <p>He said that in the scenario we are able to just put either <code>x++</code> or <code>++x</code>, <code>++x</code> is more efficient (by little, but still, in theory, more efficient nonetheless).</p>
  
  <p><strong>But I forgot why</strong>. Anyone knows? This was with Java.</p>
