Inner classes

Hi All,
I have completed the inner classes questions from the K&B and Khalid book and from Dan's website. I feel I still need more practice.
Any suggestions?

Have you tried playing with them? Writing some code? Can you write an example of all the different Inner classes without having to look at your book?

My first idea was to search the forum for all topics on inner classes. But the ratio of wheat to chaff might not be high enough. It might be too time consuming.
I try to look at any thread or inner class question that comes up at the Ranch each day. For example, Harwinder just asked a good one on local classes. You probably do the same thing already.
The best idea I can think of is to find a study partner (preferably someone who knows inner classes even better than you do). Go through the inner classes chapter of The Java Programming Language sentence by sentence. For each sentence, invent several difficult code examples for your partner.
Dan told me his questions originated when he was studying for the exam. If only we could all invent questions like he can.
