This problem is shameful, for a lot of reasons, some of them already exposed below.

We can not teach people to use Java with a problem that makes so many basic errors (Class name starting in lowercase, variable with a single letter and in uppercase, which is usually reserved for constants, bad usage of try-catch for controlling the flow of the program, etc.).

I though there was a review process or something for problems, but I have seen a few problems in the Java section that make me think otherwise...
