There a nice little site which allows you to test and refresh your Java Programming skills by giving you a series of challenges to solve. I found it quite interesting. Although it’s does not completely covers all the aspects of java programming (e.g. the OOP concepts) but normal coding concepts which involves using control statements, arrays, string processing etc. are nicely covered.
Here is the link- http://javabat.com/
(I tried to solve each one of them with a single line of code and was successful for most of the easier problems. Try out and see if it is possible for you.) Leave a comment if help is needed.
