Hai, Please suggest me the best tutorial/preparation notes (concepts & questions, exam oriented ) on the following topics : (a) Threads (b) Collections (c) Assertions [Dan changed the title to something more descriptive.] [ April 07, 2003: Message edited by: Dan Chisholm ]
For clearing thread concepts, you should read Thinking In Java. I'm a fan of it. And it's freely available. For collections and Assertions, tutorials at java.sun.com are enough for the exam. Once you get the concepts right, you can grab any of the free or commercial mock exams for practice.
