title: What does @Override mean?
body: <pre><code>public class NaiveAlien extends Alien
  {
  
      @Override
      public void harvest(){}
  
  }
  </code></pre>
  
  <p>I was trying to understand my friend's code, and I do not get the syntax, @Override in the code. What does that do and why do we need in coding?
  Thanks.</p>
