I found this link on www.sun.com . It is an article written by experts of Java. They shared a few tips but these tips are really good. I won’t be posting the tips here. It is a link to the website. The tips are not specific to any domain in java but they are very generalized and very well explained. I really liked the way the information was conveyed there.
