Simple question about this class

[kevinkhan]

When a user clicks 1 in the do while loop. it will enter case 1 and method option1(pl) will execute. After this method has exectued how does it get back into the loop and display the menu again???

public class PaymentListTester {
    public static void main(String[] args) {
        char choice;
        int total;
        // declare PaymentList object to test
        PaymentList pl;
        // get size of list
        System.out.print("\nMaximum number of payments? ");
        total = EasyIn.getInt();
        //create PaymentList object to test
        pl = new PaymentList(total);

        do {
            System.out.println("\n[1] Add a payment");
            System.out.println("[2] List all payments");
            System.out.println("[3] Get number of payments made");
            System.out.println("[4] Get total payments made");
            System.out.println("[5] Quit");
            System.out.println("\nEnter a choice [1,2,3,4,5]: ");

            //get choice
            choice = EasyIn.getChar();

            switch(choice){
                case '1': option1(pl); break;
                case '2': option2(pl); break;
                case '3': option3(pl); break;
                case '4': option4(pl); break;
                case '5': System.out.println("\n\nBYE"); break;
                default: System.out.print("\n1-5 only");
            }

        } while(choice !='5');



    }
   // Static Worker Methods

    // add payment
    private static void option1(PaymentList listIn){
       if(!listIn.isFull()){
          System.out.print("\nEnter Month: \t");
          String month = EasyIn.getString();
          System.out.print("Enter amount: \t");
          double amount = EasyIn.getDouble();
          listIn.add(new Payment(month, amount));
       }
       else{
          System.out.println("\n!!! SORRY, LIST IS FULL!!!");
       }
   }

    // display payment
    private static void option2(PaymentList listIn){
        System.out.print("\nMONTH \tAMOUNT\n"); // header
        // loop through payments in list
        for(int i =1; i<=listIn.getTotal();i++){
            Payment p = listIn.getPayment(i);
            System.out.print(p.getMonth());
            System.out.println("\t" + p.getAmount());
        }
    }

    // Get total number of payments
    private static void option3(PaymentList listIn){
        System.out.print("\nTotal number of payments made: ");
        System.out.println(listIn.getTotal());
    }

    // get total of payments made
    private static void option4(PaymentList listIn){
        System.out.print("\ntotal sum of payments made: ");
        System.out.println(listIn.calculateTotalPaid());
    }

}

It never leaves the loop, so it doesn't need to get back into it...
Or have I misunderstood your question?

[knightwriter]

I would change out the switch for a loop and then add a control variable. Or add a loop after after the switch to get back into the display menu again. Something like asking if they are done with their transaction..."y" or "n."

Oh sorry , so the break; is only to get out of the switch statement. at first i taught it was to break out of the loop.
