1-Make the subject line more descriptive of the actual question. "Core Java" doesn't tell us anything about what your question is.
2-Please restrict a single post to one or two related questions. If you have questions that are entirely unrelated to each other, please post them in separate threads, and possibly in separate forums.
Please don't take offense at these suggestions. Your questions are welcome and we'll do our best to answer them. If you follow these suggestions, your experience here at JavaRanch will be much better. [ September 28, 2006: Message edited by: Merrill Higginson ]
