Compound types include the implementation of these types, so they are similar to mix-ins and multiple inheritance of implementation.-- Cedric

callMethodWithFoo(new Foo(){count = list.size; validate = isValid;});

is pretty trivial so infering the type isn't that important I guess.]]> Mon, 16 Jan 2006 16:00:51 -0500 Mon, 16 Jan 2006 16:00:51 -0500 Mon, 16 Jan 2006 16:00:51 -0500 Jan 16, 2006 James Watson 0 Re: question http://www.theserverside.com/discussions/thread.tss?thread_id=38430 Mon, 16 Jan 2006 11:59:25 -0500 Mon, 16 Jan 2006 11:59:25 -0500 Mon, 16 Jan 2006 11:59:25 -0500 Jan 16, 2006 James Watson 1 Re: question http://www.theserverside.com/discussions/thread.tss?thread_id=38430

The thing about the Java typing system that I don't like is that you have to explicitly implement the interface.

One last thing I would like to mention James is from your posts it's seem like you think the biggest OO strength is the type safety OO give you, that everything will compile well.
What gave you that impression? It's...]]> Fri, 13 Jan 2006 11:31:02 -0500 Fri, 13 Jan 2006 11:31:02 -0500 Fri, 13 Jan 2006 11:31:02 -0500 Jan 13, 2006 James Watson 4 Re: question http://www.theserverside.com/discussions/thread.tss?thread_id=38430 BTW, if you want the best OO solution for implementing functional programming, implement the visitor pattern.

That's how you simulate double dispatch in Java, yes.

Let me explain. I spent this time posting on this thread (which is considerable) because I find that I learn a lot from it. I also hope that others gain something from me too.
