I need to figure out how to set my overall ticket limit (aticket + cticket) to 100 and if a customer goes over the limit, then they are told that they have ordered too many tickets and that they need to try again and then it loops back through until they order less than a total of 100 tickets. Can someone please help?

The following loop itself could be modified to perform this check you need :-

do {
  System.out.print("\nHow many adult tickets? ");
  atickets = keyboard.nextInt( );
  System.out.print("How many children's tickets? ");
  ctickets = keyboard.nextInt( );
  positive = true;
// Defines the invalid  boundaries (but true by definition).
// add the new condition with an "||" in this "if" condition itself
// or use another if block
  if ( (atickets < 0) || (ctickets < 0))	 {
    System.out.println("\n(You must pick a positive number): ");
    positive = false;										 
  }				
}while(!positive);

To the "if" condition just add ((atickets+ctickets) > 100) with an "||" operator, so even when the sum of the two is greater than 100 it will prompt the user the enter them again. You will however need to modify your error message to reflect exactly why the user has to input the "aticket" and "cticket" values again taking into account the new case.

@stephen84s : Yes but in this case, what happens if he inputs the number of adult tickets to be 110 ? You still ask him for the number of child tickets, which since he has already jumped the maximum count is wrong on our part. If he enters the no. of adult tickets to be greater than 100 he should be warned of the limitation there itself rather than proceeding.
Take a look at this post for a solution.

Yeah thats correct, but I assumed the thread starter will figure out what additional checks to put, so I just pointed out where to put his checks.
