6,919 PointsWouldn't numeric prompts be more user friendly? How will the data be persisted?
I think that a menu system with numeric options is easier, e.g
1 - Add new song 2- Edit song 3 - Remove song 4 - Admin tools 5 - Quit
Also, what if the user doesn't enter anything or a bunch of spaces only? Will that crash the application? Shouldn't some form of validation be performed?
A Karaoke machine that loses its data each time the application is exited or crashes seems less useful than one that stores and retrieves data. Can this app possibly use the Serializable methods of writeObject on an ObjectOutputStream and readObject on an ObjectInputStream?
Thanks

For input validation read about exception hadling.... Certaninly your app will crash if unexpected data is introduced. https://docs.oracle.com/javase/tutorial/essential/exceptions/

4,780 PointsI tried the Integer way and I got it to work but when I selected a valid choice (1 for add 2 for quit) it would go to the default of the switch and say either 49 or 48 wasn't an acceptable response or something of that nature. I did with with the Integer class instead of int that could be why may retry it with that and see what happens.
