A2. A telecom tycoon selling charging vouchers with different values to their users for the prepaid card service via an online system. Whenever a user enters the system, it lists all charging vouchers with different values for user to select the voucher that is required. After the user has selected a voucher and proceeded to checkout, the system asks the user to enter hisher mobile number.

Based on the given class diagram and the test program CustomerCentre.java, implement the classes Customer, ElectricalAppliance and Television in Java.
Note: Apart from the attributes and methods to classes Customer, ElectricalAppliance and Television, it may be necessary to add attributes and methods to classes Customer, ElectricalAppliance and Television for implementing the onetomany association and the
basic getterssetters.15 marks

Section B 60 marks
This section contains THREE questions.

Answer ALL questions.

The problem statement for the questions in Section B.
Online shopping getting more and more popular because of the low price of the items being sold. However, the transportation fee for a single item is quite expensive normally. To cope with the issue, the consolidated shipment is one of the costeffective way. A consolidate shipping company provides an Online Shipping Management System OSMS for her users to manage the items they bought from various online shops.
Anyone would like to benefit from the system will required to register a member account with hisher email address, mobile phone number and at least one shipping address. After successful registration to the system, an activation code will be sent to the members mobile phone and the member is required to enter the code to the system to activate hisher account. After the activation is done, the member will receive a welcome email.
Whenever the member buying things from different online shops, they should instruct the items to be sent to the consolidate shipping companys collection point. At the time when the items are delivered to the collection point, the member inputs the delivery order number to the system and the system will tracks if the items are delivered to the collection point.
The member can login and check the items statuses at any time. When the items are shipped to the collection point, the items will be weighted, and the staff will input the corresponding items weight in the system and member will get this information when heshe checks the statuses of the items.
When the member logged in to the system and checks that items are delivered to the collection points, the member can then select multiple items to be consolidated and start shipping out by pressing Consolidated Shipment. The system then asks for the recipients name and select the shipping address from the registered list. The member can register a new shipping address before submitting the order. After that, the member clicks Submit button to send out the shipping order. The system then sends a delivery request to the shipping agency and notifies the SMS gateway to send a SMS notification with the delivery order number to members mobile phone. Finally, the system displays the order details. The member can login to the system to check the order status before the items are received.
