Activity
Learning outcome 1: Demonstrate understanding of classes, constructors, objects, data types and instantiation; Convert data types using wrapper methods and objects.
Learning outcome 2: Independently analyse customer requirements and design object-oriented programs using scope, inheritance, and other design techniques; Create classes and objects that access variables and modifier keywords. Develop methods using parameters and return values.
Learning outcome 3: Demonstrate adaptability in building control and loop structures in an object-oriented environment; Demonstrate use of user defined data structures and array manipulation.
Project: Implement a Class Hierarchy for Shapes
Problem Description:
Design and implement a class hierarchy for shapes using Java inheritance. Your solution should include the following classes:
1. A Shape class, which represents the base class for all shapes. It should have a field for the color (treat it as text) of the shape, as well as methods for calculating the area and perimeter of the shape.
2. A Rectangle class, which extends the Shape class and includes additional fields for the width and height of the rectangle.
3. A Circle class, which extends the Shape class and includes an additional field for the radius of the circle.
Your solution should also include a main method that demonstrates the functionality of the shape system. This should include creating fiveinstances of the different classes, putting them into an appropriatearray, calculating the area and perimeter of each shape, describing the color of each shape, and printing out the results using a loop. You should also include an UMLdiagram design of your classes.
Your code should be well-documented and follow Java coding conventions.
Analysis/Design/UML:State what you need to implement, methods required and UML diagram ... etc.
Coding: (Paste your code here, including Shape, Rectangle, Circle and main class using Courier 10pts)
