Transcribed Image Text:Part 1. Create a Parent Class Create a complete Java class Computer that can be used to create the object as described below: A Computer has-a: - Model - Brand Name Manufacturing Date Number of cores a) Add all instance variables (data encapsulation is expected) b) The class must have getters and setters for all instance variables c) The class must have a no-arg and another constructor that receives input parameters for each instanc variable. d) Implement toString() method for this class to print the contents of the data fields. Part 2. Test a Parent Class Write a Java program TestComputer, which creates three Computer objects with the information below: a) Model Number: Inspiron 1545 Brand Name: DELL b) Manufacturing Date: April 1, 2020 Number of cores: 2 Model Number: A2338 Brand Name: Macbook Manufacturing Date: March 31, 2020 Number of cores: 4 c) Create your own Object. You can mimic your actual personal computer or use a no-args constructor. Part 3. Create two Child Classes Create two Java classes, Desktop and Laptop that both are subclasses of Computer. a) A Desktop has additional instance variables: width and height (data encapsulation is expected) b) A Laptop has an additional instance variable, weight (data encapsulation is expected) c) Write constructors for both classes that require input for all their instance variables (including Model Number, Brand Name, Manufacturing Date and Number of cores) and also no-args constructors. d) Create getters and setters for all instance variables for both Child classes. e) Create toString() methods(overridden) in Desktop and Laptop classes Part 4. Test Two Child Classes Test your newly created classes inside the same TestComputer program you previously created: create two new Laptops and two new Desktop with the data of your choice. You can use and call toString() method to print their complete description. Hint: Make sure to avoid redundancy in your code-no fields implemented in the Parent Class should be repeated/reimplemented/redefined in children
