Question

I am having a small problem I am trying to print the contents of a couple of variables which are located in a a private method. but I simply keep getting ‘Can Not Find Symbol’

Below is the code that I am trying to read the data from (including the println) also I am very new to java.

private void createBooking()
{
     String title;
     String firstName;
     String lastName;
     String bookingNo;
     String roomType;

    System.out.print("Enter title: ");
    title = keyboard.next();
    System.out.print("Enter first name: ");
    firstName = keyboard.next();
    System.out.print("Enter last name: ");
    lastName = keyboard.next();
    System.out.print("Enter booking number: ");
    bookingNo = keyboard.next();
    System.out.print("Enter room type: ");
    roomType = keyboard.next();


    aBooking = new Booking (title, firstName, lastName, bookingNo, roomType);

}

public void printCustomerName()
{
    System.out.println (createBooking.title);
}

You probably want to put these variables as member variables, and then simply access it without using the .-operator.

class BookingClass {

    // You also seem to need the following:
    Booking aBooking;

    String title;
    String firstName;
    String lastName;
    String bookingNo;
    String roomType;

    private void createBooking() {

        System.out.print("Enter title: ");
        title = keyboard.next();
        System.out.print("Enter first name: ");
        firstName = keyboard.next();
        System.out.print("Enter last name: ");
        lastName = keyboard.next();
        System.out.print("Enter booking number: ");
        bookingNo = keyboard.next();
        System.out.print("Enter room type: ");
        roomType = keyboard.next();

        aBooking = new Booking(title, firstName, lastName, bookingNo, roomType);
    }

    public void printCustomerName() {
        System.out.println(title);
        // ...should perhaps be
        // System.out.println(firstName + " " + lastName);
    }
}

Since you do create a Booking instance however, you may want to get rid of title, firstName, lastName, bookingNo and roomType and put them in the Booking class instead. And then access them through aBooking.getTitle() and so on…
