You almost certainly have a brackets problem, either one bracket too many or one bracket too few. Format and use code tags to preserve that formatting.


[code=JAVA]
// code here
[/code]


Without indentation, your chances of finding the bracket problem go way down. That's why consistent indentation is key.

First step: comment out everything inside the class except main and the constructor, and comment out everything inside the constructor. That should compile and run perfectly. It won't do anything, but it'll compile and run. If it doesn't, you've found your bracket problem already. If it does, start uncommenting your functions till you find the bracket problem.

That's where the code tags help.


[code=JAVA]
// code here
[/code]

or

[code]
// code here
[/code]


Here's an example.

Java-specific code tags (indentation, syntax highlighting, line numbers):

JAVA Syntax (Toggle Plain Text) 
  1. public class HelloWorld
  2. {
  3.     public static void main (String args[])
  4.     {
  5.         System.out.println ("Hello World");
  6.     }
  7. }

Non-Java-specific code tags (indentation, but no highlighting or line numbers)

Java Syntax (Toggle Plain Text) 
  1. public class HelloWorld
  2. {
  3.     public static void main (String args[])
  4.     {
  5.         System.out.println ("Hello World");
  6.     }
  7. }

No code tags (looks terrible):

public class HelloWorld
{
public static void main (String args[])
{
System.out.println ("Hello World");
}
}

Another tip regarding posting on forums. Try not to mix spaces and tabs. A tab on Daniweb is eight spaces. It's usually four or five spaces in most IDEs, so what lines up in an IDE like NetBeans may well not line up when you post here. Solution? Convert tabs to spaces before pasting. Most IDEs have an option where you can change tabs to spaces fairly easily.

Look at lines 96 - 112. The starting bracket is on line 96. The ending bracket is on line 110. Lines 111 and 112 are not in the printReceipt function.

I assume the while statement on line 105 is supposed to go to line 110, but there is no STARTING bracket on line 105, which I assume is an oversight?
