This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I liked the question of Praveen. And it inspired me to this exam question.
What happens when you compile and execute this code? (JSE 1.5)
Choose all that apply!

You will find this topic written about in the K & B book (or any good Java book) together with the comment to the effect of "it may be legal, but that does not mean it's good programming style".
Please do not use this topic as a general puzzlers topic. Keep topics specific to one issue. Also consider whether the issue is SCJP specific or whether it is a puzzling aspect of Java which could be equally well discussed in one of our Java In General forums (Beginner, Intermediate, Advanced).
If you are really interested in such puzzlers, treat yourself to a copy of "Java Puzzlers" coauthored by Joshua Bloch. [ September 02, 2006: Message edited by: Barry Gaunt ]
