thanks for the reply.
i moved the u.doLogon() + a.doLogon() after the username was set. when i tried to log on to my system the first time, 2 main menus appeared instead of one. i removed the for loop code. but when i tried to compile the video library menu program the second time, i got the following errors (both the errors and the modified LogOn.java program are shown below). i must have done something stupid now. should i put the for loops back into the code + modify the User and Administrator classes so that only one main menu appears when i log on to my system?
