this program is havin errors pls can u rectify it and send me back as soon as possible pls

[Norm]

this program is havin errors

Please explain and post the full text of the error messages.

Please edit your post and wrap the code in code tags. See: BB Code List - Java Programming Forum

[Fubarable]

A constructor must have the exact same name as the class name.

ImplementationTexas is not the same as rfid.

Don't double post. I've merged the two threads (which in all probability have the same code, but a forum isn't a good place to ask for help with reams and reams of code -- IOW tl;dr).
