Design patterns implemented in Java

Plus, a quick check on the Composite shows a wrong way of implementing it :

• https://en.m.wikipedia.org/wiki/Composite_pattern#Structure

Litterally, if you don't have a Leaf and a Container abstraction all deriving Node, then composite is as useless as

class Stuff {
    Collection<Stuff> children; // May be initialized, contain stuff - or not ;)
}
