Whenever it comes to string handling in java the following questions are frequently asked,
1. What do you mean by immutability? And how can one make an immutable class?
2. What are the performence tradeoffs between string concatenation and appending strings in StringBuffer?
3. What if i use .equals method with two strings with same content and the same for StringBuffer? Justify your answer.
I'm not giving answers to these questions hereby, You just try to answer these questions and email me.

Regarding use of equals on StringBuffer and String : Since StringBuffer diesn't override equals therefore such a comparison will always give false in case of StringBuffer.
