Hi,
Welcome to JavaRanch!
I'm assuming "TCS chennai" is your new employer; perhaps it's your new school. But in either case, we have a forum called
Jobs Discussion where these questions would be on-topic. The "Java in General" forums are for asking programming questions about the
Java language itself.
Anyway, I'm moving this
thread to the "Jobs Discussion" forum for you -- go find it over there.
