Java: inherits a generic type

Possible duplicate:
Extension from a common supertype?

Hello everybody. I came from C ++ and I loved working with templates. I would like, in Java, to β€œinsert” a node into the inheritance tree at a specific point. ... I think the code will be more explicit:
public class MyClass<E> extends E {}

This works fine with C ++ templates, but java gives me "cannot refer to type of type as supertype". Is there any way to do this in java?

Thank you for your help;)

To understand the problem with the code you tried, consider what would happen if you Ewere, say Integer,?

You can do what you want with nodes that contain common data:

public class Node<T> {
    T data;
    // other tree bookkeeping fields
}

Then you can define subclasses:

public class ThreadedTreeNode<T> extends Node<T> {
    // even more bookkeeping fields
}
