Generic Types

Hi there, hope you guys can help :)
I have a generic class:
public class Tree<T> {
...
private Node<T> root;
public Tree(T data) {
root = new Node<T>(data);
}
...
}and a class which extends this class:
public class TicTacToeTree extends Tree<Board> {
public static void main(String[] args) {
// This does not work
TicTacToeTree tree = new TicTacToeTree(new Board());
// This does work
Tree<Board> btree = new Tree<Board>(new Board());
}
}I get the following error message "The constructor TicTacToeTree(Board) is undefined". I can't see why it doesn't work with the TicTacToeTree but does if you create the tree with type Board.
Any help would be appreciated.
Thanks
