OBJECT ORIENTED PROGRAMMING FUNDAMENTALS (java)

Part 1: Develop an object-oriented console program in Java language (40 marks) Background: You are requested by a customer to build a system myTrack to record the vaccination status and check-in activities during the COVID-19 pandemic. The system has the similar functionalities as the mySejahtera application as shown in Figures 1, 2, 3, and 4.

The myTrack system has the following requirements: The system should be able to store and display the user profile details as shown in Figure 1. There are two types of users: normal user and pregnant women. The system should be able to record additional information for pregnant women, such as the months of pregnancy, and last check-up date. Each user can view their risk report, digital vaccination certificate, and check-in history as per below: The system should be able to display the risk status report that contains the information of the risk status, current location risk, high risk dependent, and a QR code as shown in Figure 2. The system should be able to display the digital certificate consists of the users doses information as shown in Figure 3. The system should be able to display a history list of the places that the user visited before, with each of the check-in record contains the name of the place and the visited date. Please complete the following questions: a) Identify and design the classes that fulfil the above requirements by drawing the UML class relationship diagram with required data members. You should design your classes for optimum maintainability and reusability with the best practices of object-oriented techniques you have learnt. Use inheritance whenever appropriate. b) Create the classes that you have designed in part 1(a) in Java language. Complete the classes with constructors, methods, setters and getters. c) Create a driver class (main application) to demonstrate the followings: a. Create one normal user and one pregnant user by using an ArrayList as storage and print their profile (refer Figure 1). b. Print the risk report for one of the users (refer Figure 2). c. Print the digital certificate with the doses of vaccination information for one of the users (refer Figure 3). d. Print the history list with at least two visited places for one of the users (refer Figure 4). Note: No GUIs are required. The QR code can be represented by a String
