title: Java: Deriving from a generic List/Collection
body: <p>I have a little problem understanding the Java language</p>
  
  <pre><code>public class PhonebookEntryList extends List&lt;PhonebookEntry&gt;
  {
      public PhonebookEntryList(String filename) throws IOException
      {
          //loadListFromFilename(filename);
      }
  
      public void saveListToFilename(String filename) throws IOException
      {
          //Do something to save it to a file
      }
  }
  </code></pre>
  
  <p>I can't do this, because List is a generic Type (of course). I know what that means, but at the moment I can't think of a Solution for this problem.</p>
  
  <p>Can you help me to solve it? Thanx!</p>
