I am one of the moderators of the JavaRanch forums. Here on JavaRanch, we have a naming policy. We want the users of JavaRanch to use a real-sounding name as their display name.
Unfortunately, your name "bengaluru guru" does not comply to the naming policy. Your display name should consist of a real-sounding first name, space, and a second name. Not only a first name, no obviously fake nickname, no initials only for the second name.
Please read the naming policy carefully and change your display name. You can change your name by editing your profile.
Please note that we are taking the naming policy seriously. If you do not change your display name, your account on JavaRanch might be locked.
