My program "should" 1. Ask for totally number in party 2. Ask if this partyNumber is correct 3. Get Name 3. Get Entree Order 4. Get Side Order 5. If diner number < number in party 6. Go to Step 3.
I've been working in this for forever and I'm at the point where I'm completely confused with what I'm doing. I need a walk away from it from an hour.
The main thing I can't figure out is I continue get Diners names and there orders and present the output. If I choose only one diner if will produce output but if I choose 2 or more people in Party I don't even get any output and I can't understand why? Also if I do say that there is only one person in the party it will produce input but for some reason it outputs the dinner entree of the Diner 3 times?? No side order gets output in my JOptionPane.
Hoping someone could help me a bit with my problems. I've reached a point where I getting completey lost. Any guidance or suggestions would be greatly appreciated.
The output which is resulting from the code is confusing me the most.
P.S. My GUI is pretty wacked but thats another issue in itself and I'll worry about that later. Thanks again.

Looks like you have two different class definitions for Menu. Maybe you can repost just the one you are using? Also, if you use the java tags (see Formatting Your Post at the bottom of the page, when you are submitting your post), the code will be a lot easier for people to read.
