                           System.out.print("\nProcess Another    Ticket?('y'/'n'): ");
                        again = Keyboard.readChar();
                        Keyboard.skipLine();
                        again = Character.toUpperCase(again);


          }while(again == 'Y');



     }                        //close main method

 }                            //close class

OK i posted my program, its Just completed :D .. Compiles and runs fine.

Only problem I have is in the Process another ticket part. I need to do an "if" statement for it, and wrap it in a "do while", so that only the characters Y and N will be allowed .. (not case sensitive)


So i tried

         do{
                                    ...................../rest of program here


                                         do{
                                   System.out.print("\nProcess Another Ticket?('y'/'n'): ");
                        again = Keyboard.readChar();
                        Keyboard.skipLine();
                        again = Character.toUpperCase(again);

                                                   if(again != 'Y' || again != 'N')
                                                        {
                                                             System.out.print("ERROR: ONLY THE CHARS Y AND N ARE ACCPETED")
                                                         }


                                            }while(again != 'Y' || again != 'N');


          }while(again == 'Y');

But when you do that. It doesnt stop loopin the Process another Ticket sentance :evil:

Any help is much appreciated.


BTW, I use a Keyboard.class to read in from the Keyboard, but any other method is fine .. Also I only suplied the whole program at the start cause Id find it easier to Read that way.

Thanks in advance

Oh i just figured it out :D

while(again != 'Y' || again != 'N');

That was my problem line

while(again != 'Y' && again != 'N');

This seems to fix the problem, but im not sure how??

If someone could explain that I would appreciate it,

Thanks again,
Mark

not equals y or not equals n

Well, that's just about anything you can enter, isn't it? If it's y it's not n and so valid, since only one side of the expression needs to be valid, and vice versa.

not equals y and not equals n

Now when it is a y or an n, it is still valid for one side of the expression, but, because it's an and, it needs to be valid for both sides of the expression.

Ahh i see.. yeh i get you.

Cheers mate.. much appreciated
