title: What is a super constructor?
body: <pre><code>public class HalloGUI extends JFrame{
      
      public HelloGUI(String title)
      { 
       // Some explanation about this method 
       super (title);
       /*Why super(title)? What is the usage of super() */
  
       /* Here some other codes */
      }
      
  }
  </code></pre>
  <p>I don't understand the usage of <code>super(title);</code>. I know that title is a parameter of the method super(), but why does ine use it? Do you really need to use it? What is the function of <code>super(title);</code> in this code?</p>
