How do I override a method of an Inner Class?

[Matt Wilcko]

Hi,
I am trying to override a method that belong to an inner class of the BasicTreeUI class. How do I do that?
Thanks

When a base class is extended and its nested classes are re-defined in the subclass (even with the same name as the nested class in the superclass), these nested classes do not automatically inherit from the nested class within the superclass. Instead, the re-declared inner class must specifically extend the Base.Nested class. For example...

class Base{
  class Inner{}
}
 
class Derived1 extends Base{
  //Case 1: not re-declared -- Inner is inherited
}
 
class Derived2 extends Base{
  //Case 2: re-declared -- does NOT inherit from Base.Inner
  class Inner{}
}
 
class Derived3 extends Base{
  //Case 3: re-declared with extends keyword -- does inherit
  class Inner extends Base.Inner {}
}

So to override a method in a nested class, I imagine you need to specifically extend that nested class...

class Outer {
  class Inner {
    void meth() {
      System.out.println("Outer.Inner.meth()");
    }
  }
}
 
class Ext extends Outer {
  class Inner [B]extends Outer.Inner[/B] {
    void meth() {
      System.out.println("Overridden.");
    }
  }
}
 
class NestTest {
  public static void main(String[] args) {
    Outer.Inner i = new Ext().new Inner();
    i.meth();
  }
}
