Create a Java Code Computer Programming Task-Allan Hancock College .

My program will serve an owner for a concert venue to count the profits for each concert he has. I will use a main class and of course a class to count the whole profits calculating the event ROI. I will create a concert class, a custom class and concert objects have: name, date, time, location, cost ,seats etc. Also customers objects have: name, address, number , age, etc. customers can attend multiple concerts already defined then the gui will let you register customers for concerts. Then you compute ROI, upon close, save customer info to file (reload next time}
