A fast food business McBurger Queen Inc. wants to try out a new concept in
drive through orders. Instead of cars driving up to a window and ordering,
car customers park in designated parking lots. An attendant with
a hand-held device will approach the parked cars to take orders and transmit
them through wireless and collect the money (or charge). When the order is
ready it will be delivered to the car. McBurger Queen Inc. has hired you
write this ``mobile application'' in Java. They have designed the user
interface of the hand-held device according the specifications given by
an ergonomist. I have provided the Java applet that displays this
interface.
Type it in and run it. Task assigned to each of you is to come up with
the program that makes this interface work.
