There aren't many rules that you need to worry about here on the Ranch, but one that we take very seriously regards the use of proper names. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.
In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.
"Deepthi M", my request that you change your display name was not a suggestion. Please modify your display name as instructed prior to your next post. Accounts with invalad display names are removed.
