Need good source of practice programs in Java

[Sedgie!]

I'm just learning Java on my own, with the help of Paul Deitel's "Java: How to Program". The explanations are great, but there aren't enough practice problems. Does anyone know of a website that has a lot of practice programs for beginners?

The online judge Universidad de Valladolid has piles of ACM problems, and an online system that grades 'em. Plus a forum to ask questions.
