Hey!
Ramanathan Subbarayan, this is off-topic for SERVLET-INTEREST.
I couldn't let it slide though because there are two glaring
mistakes here. Be careful when you respond to a question
that you are absolutely certain that you are correct.
There is no method setSize().
I am guessing that you are referring to setLength().
This is also is not correct.
If you are worried about allocating memory, you are
better off using delete() ("I think. I don't have the JDK
source code available to be certain. You might want to
check on your own. Let me know if I am wrong.).
With delete(), you are just removing the characters and
not changing the buffer size.
Sans adieu,
Danny Rubis
