Using Java 7, given the class file:

import javax.swing.*;

public class KList extends JList {
     ListModel model = new DefaultListModel();

     public KList() {
         setModel(model);
     }
}

compiling it gives me

C:\com\knutejohnson>javac -Xlint:unchecked Klist.java
Klist.java:7: warning: [unchecked] unchecked call to 
setModel(ListModel<E>) as a
  member of the raw type JList
         setModel(model);
                 ^
   where E is a type-variable:
     E extends Object declared in class JList
1 warning

How do you extend this class with generic types?

Thanks,
