Answer 1

For your example you might want lists (ordered children). Otherwise you could use it pretty much as-is:
final Node root = new Node("Pyramids");
final Node node2 = new Node("Built");
final Node node3 = new Node("Giza");
final Node node4 = new Node("3000 years ago");
root.getChildren().add(node2);
node2.getChildren().add(node3);
node2.getChildren().add(node4);(Edit)
Just to clarify, you would build the above tree however you want to, but would only need to retain the reference to the "root" node in order to pass it into search methods.
I should also point out that if you're planning to do a lot of this sort of thing and you're not committed to using Java, you should probably consider using LISP for which this sort of problem is pretty much its raison d'etre.
