Can someone help me with these errors?

You can't declare methods within other methods, so those that you have crammed into the switch statement have to be moved out.

I took the other methods out and still have errors.

Walk through and match your braces. Maintaining good, consistent indentation helps a lot to see things like this.

Also be sure to read the errors carefully because they contain line numbers where the problems occur. "Illegal start of expression" is going to indicate an improperly terminated block or expression prior to the point that the compiler complains.

From what I can tell, I have a closed brace for every open brace.

Well, I'm going to "guess" that your error is around line 128 (you didn't post the error message) and suggest you look more closely at main().

The error message is still the same. Illegal start of expression.

Of course it is, unless you fixed that missing brace from main().

You know, it's getting pretty tough to see over your shoulder and know what you're doing there. You might try reposting the code if you fix something. And walk through every brace and find it's matching closing brace.

I'd say in line 116 rather you ended with an extra ")" or u didnt use indentation for it, check it out.
