Chapter 7, Problem 7.4E
Program Plan Intro
Hierarchy Chart:
- The hierarchy chart is for top-down
programming . - The hierarchy chart is also known as structure chart.
- It is mainly used to visualize the modules used in the program.
- A module is a set of program statements that is used to perform a specific task.

A shape can be classified into 2-D and 3-D. Design an inheritance hierarchy that will include different kinds of 2-D and 3-D shapes. Make sure you identify at least five other classes of shapes.
Inheritance makes it more difficult to design object class tests. Explain.
Implement the following hierarchy shown in Figure 1, using Java Inheritance.
The class Student is the parent class. Note that all the variables are private and hence the child classes can only use them through accessor and mutator methods.

- JAVA Create a class representing the student. Define all the properties you can think of. Define all methods the student class might have. (You can be inspired by the UML diagram but add some more methods you come up with). You can simplify the university management system by modeling it as an array of Students. Define all the methods the university management system should have.arrow_forwardConsider a three-dimensional (3-D) geometric shape as a concept. Any such 3-D shape will have a volume and surface area, but until you know the nature of the shape and its attribute dimensions, these will be abstract in nature. Design and implement an inheritance hierarchy starting with a 3-D shape, then a set of at least three derived classes that define regular 3-D shapes such as a cube, sphere, cylinder. Include a UML class diagram showing the design. Any general 3-D shape will have a name, but few other attributes. For each derived shape, store fundamental attribute data about its dimensions, and provide methods to access and modify this data. In addition, provide appropriate methods to compute each shape’s volume and surface area. For example, a cube has a volume of s3 where s is the length of a side, whereas a sphere has a volume of 4πr3/3 where r is the radius. In terms of style, every class should have constructors and a toString() method that properly uses inheritance.…arrow_forwardIn this part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods. You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop class in part II should have given you an idea of inheritance and polymorphism. Three sub classes, one class against each category (Computers, Laptops and Accessories), should contain appropriate constructors, instance variables, setter and getters methods and overridden methods for getItemName(), getItemDescription() and get_Item_details() method. You should be creative and come up with your own ideas of sub-classes.
