Java Project

I need a program, 3 classes: [login to view URL] [login to view URL] [login to view URL] [login to view URL] = Validates the time [login to view URL] = Form DATA etc... [login to view URL] = Runs the program The forms = 1: First & second name inputs 2: Start & finish time inputs (24hr clock) End display = First & second name How many hours form start to finish The classes need to be called, I would like the program to be as simply as possible so one form for names (click OK) second form for time inputs (click OK) then Details form (First & second name & How many hours form start to finish are displayed) e.g. Name: John Jones Hours: 9:33 All entries must be validated so only valid 24hr clock time inputs & only letters for the name inputs. Thats it. Thanks........
