title: super-constructor if there is no super class?
body: <p>I found a class like this:</p>
  
  <pre><code>public class Computer implements Serializable {
  
          private static final long serialVersionUID = 1L;    
  
          //...
          public Computer() {
              super();
          }
          //...
  }
  </code></pre>
  
  <p>Can someone explain me, how this works? The class isn't inheriting any super class and there could still be "super();" in the constructor?</p>
