The aim of this project is to create a graphical user interface to the application and also store/retrieve the data in external binary files.
In this assignment, you need to create a graphical user interface to this application. In this interface application will need to make sure that all the methods given in the RestManApp class has a graphical user interface interaction. It need to choose appropriate Swing components to implement the user interface. Make sure that you used at least the following Swing components: JFrame, JButton, JLabel, JMenu, JMenuItem, JFileChooser, JPanel, JTextArea, JTextField, JCombobox, JScrollPane, JTable. The overall requirements can be summarised as follows: • When the application starts,it will need to ensure that you show the relevant options to the user – all the tasks they can complete with this application. • It need to make sure that you have used all the relevant components for entry.
The overall requirements are based on this class diagram, which is also summarised below: • The main application called ResManApp will be used to maintain information about staff and customers. ResManApp will also have the main method and will provide the overall interaction with the application. Therefore, this class should include the main method where an instance of this class is constructed and the menu of commands is displayed to the user. The required methods are as follows.
o menu(): This method will display the interaction menu to the user;
o addStaff(): This method will add new staff to the list of Staff maintained;
o deleteStaff(): This method will be used to delete a staff.
o listStaffDetails(): This method will display the details of a staff (In the previous assignment, this was referred as getStaffDetails).
o addCustomer(): This method will add a customer.
o deleteCustomer(): This method will delete a customer.
o addBooking(): This method will receive the details of a customer and create a booking for that customer. The method needs to also get the relevant booking details.
o listCustomerDetails(): This method will display a customer details (In the previous assignment, this was called getCustomerDetails).
o displayCustomerLastBooking(): This method will display the most recent booking done by the customer.
o listCustomerOrders(): This method will display the orders made by a particular customer (In the previous assignment, this was referred as getCustomerOrder).
o listStaff(): This method will list all the staff.
o listCustomer(): This method will list all the customer.
o exit(): This method should terminate the program.
o addOrder(): This method will get the details of a customer and an order, and will create an order for that customer. In this case, the order type has to be specified, if it is online then an online order should be created. If it is being done within the restaurant, then it should be an InRestrOrder.
o listAllSaffSalary(): This method will display the salary details of all staff in the application. Depending on whether the staff is junior or senior, the salary calculation will be done via getSalary() method specified in the interface as follows: § If the staff is a seniorthen the monthly salary is calculated as follows: for every year who has been a staff (currentDateStartDate to find the number of years) who gets %10 increment on the grossSalaryYearly. This will be divided by 12. For example, if the employee is working for 2 years and the grossSalaryYearly is 12000, then he will have a salary of 1200 per month. This is because he received 1200 for the first year and 1200 for the second year as increments. § If the Staff is a junior, then the monthlySalary value will be displayed.
o listAllOrder(): This method will display all online and in restaurant orders that have been made. This will display all the orders made within the rest. and their associated bookings (if it exists). Please note that an in restaurant order can be made without a booking.
o addOrderOfBooking(): This method will get the details of a customer and a booking, and will create an order for that customer and booking. Payment interface has a method called “processPayment()”. Since in this a gui-project, we are not actually going to process payments, it just need to implement it in a simple way to display a message on the screen.
