class, interface, enum expected error with My INventory Program

[enfamos]

I have asked my instructor to help me with this error so I can move on to the next part of the program which is due Sunday, but no help to give I guess my problem is that when i try to compile my program I get a class, interface,enum expected error on lines 217 and 218.
import javax.swing.*;
import java.awt.event.*;
my code is posted all help will be greatly appreciated.

I just hope you actually split it in appropriate classes Inventory, Cameras, DigitalCameras and Inventory_Gui and not tried to compile and run it as one class or you would look really foolish...

Well guess I am foolish because I Thought I had split the code in to classes. The code work before I added this section. Or is it that I did not split that section in to classes.

[peter_budo]

Once you split code into 4 classes there are 3 errors on compile of Inventory_Gui to do with commented text actually on uncommented line (It could be also because of copy and paste here) then on next compile there is 22 errors to do with things not being implemented in classes or mistyped

[JamesCherrill]

When you split the code into classes you ended up with "import" statements in the middle of your file. That's illegal, they must be the first thing in the file (except for a "package" statement).
So either you just put the imports at the beginning and leave all your classes in 1 file, or you split the classes into different files, each with their own imports.
How many files is up to you, except that any class declared "public" must be in a file with the same name as the class - hence every public class must be in its own file. Non-public classes can go where it suits you, according to your package design.

[peter_budo]

@JamesCherrill you need to split on 4 classes then imports are in right place ;)

[JamesCherrill]

Yes, sure, that's a good solution. As there's only 1 public class the single file solution is also valid. I only posted because it wasn't clear to me that the O/P had understood why his original lines 217/218 were invalid.

Thank you both for your post I never did get it and at this point Im starting to have a break down so I am thinking it is over for me in this class which sucks cause I made it this far.
