On your way in you may have missed that we have a policy on screen names here at JavaRanch. Basically, it must consist of a first name, a space, and a last name, and not be obviously fictitious. Since yours does not conform with it, please take a moment to change it, which you can do right here.
"Amit S", Ulf's request that you change your display name to adhere to JavaRanch standards was not a suggestion. Valid display names are mandatory for participation on the Ranch. Please change your display name as instructed prior to your next post.
Your display name must be a first and a last name separated by a space character, and must not be obviously fictitious. Initials in place of a last name are not acceptable.
Be aware that accounts with invalid display names are removed.
