Problem with menu-driven program, please help

[ZimbuTM]

Hi all. Basically this program is there to test an already created class. GDate deals with lots of date related methods, stuff like finding yesterday's date, tomorrow's date, etc. It's for an assignment.

I'm having a problem with two things here:

1. I can't figure out how to read the next CHAR from the scanner. I can do int and strings just fine, but I'm confused about chars. (I've tried nextChar(), but that doesn't work).

2. Now using this code below, I get this error when I try to compile: [Nevermind, found out that strings are not allowed in switch statements, I have to make it char, but this comes back to problem 1 up there]

incompatible types
found : java.lang.String
required: int
switch (userChoice)

I figured that using strings would be fine in a switch, but I guess I was wrong, can someone point me in the right direction?

A char is an int by another name. You should be able to cast back and forth between them.
