title: Java interface methods never used
body: <p>So, I started using <strong>interfaces</strong> in <strong>Java</strong> a while ago. I have already created one, and I have a <strong>class</strong>, that <strong>implements</strong> that interface.</p>
  
  <p>So this is the interface itself: </p>

  <p>And this is the class that implements the <strong>Actor interface</strong>:</p>

  <p>But, as you can see in the first picture, no methods are used, ecxept for <em>create()</em>. The most strange thing is that everything works absolutely fine! Only these underlined words freak me out a bit)</p>
