Why have you changed your name? Please change it to one that conforms to our Java Ranch Naming Policy.

Thanks,

"wolfoxer java" you are required to use a proper display name that conforms to our naming policy. You have now used two obviously fictional names in addition to another you have used. As the naming policy states your access to this site can be blocked. Please change your displayed name to a first-name second-name pair, preferably your real names.
Thankyou
