catch all

Hi

have been doing a assignment which is running fine apart from one issue on my first menu the user can use 5 options 1,2,3,4,5. but if the user uses a letter by error than oops it all crashes is there a way I can catch everything except 1,2,3,4,5 I thought the default in the switch would of dealt with it but that will only deal with the numbers miss typed.

Thanks

Without code its difficult to pin down the problem, but my guess is you are parsing a string into an integer...with a NumberFormatException being thrown when you attempt to do so on a letter/string. See the following link to figure out how to either catch exceptions or otherwise validate input:
