This is an interesting pattern. I am unsure though in what circumstances this pattern should be applied. Clone is almost always more complicated to implement then a constructor.

Anyone have any other good circumstances for this pattern?

Eagerly looking for reply exclusively for this.

Very good explanation. The

Very good explanation. The key point is this:

clonedAnimal = (Animal) super.clone();

which can be mimic using constructor-like objects creation like:

Object objA = new Object("chicken");

Object objB = new Object("sheep");

but of course it serve a different purpose though. Nice one!

Nice read thanks. I really
