gui's event driven environments. is, unlike console program where, typically, program moves 1 sequence of instructions another, gui's "wait" kind of event occur , respond events.
in swing, don't need wait, taken care you. need able do, respond appropriate events occur.
take closer @ creating gui swing more details.
the basic idea devise way 1- put options 1 screen , 2- respond actionevent when occurs , update state of program when does.
