Chapter 8, Problem 2P
Define a class named Doctor whose objects are records for a clinic’s doctors. Derive this class from the class Person given in Listing 8.1. A Doctor record has the doctor’s name—defined in the class Person—a specialty as a string (for example Pediatrician, Obstetrician, General Practitioner, and so on), and an office-visit fee (use the type double). Give your class a reasonable complement of constructors and accessor methods, and an equal method as well. Write a driver program to test all your methods.

Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter
and setters for the base and the height. (Remember class variables are private.) The class
should include a two-argument constructor that allows the program to set the base and
height. The constructor should verify that all the dimensions are greater than 0. before
assigning the values to the private data members. If a side is not greater than zero, set the
value to -1. The class also should include two value-returning methods. One value-returning
method should calculate the area of a triangle, and the other should calculate the perimeter
of a triangle. If either side is -1, these functions return a -1. The formula for calculating the
area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for
calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default
constructor that initializes the variables of the base, height to -1. To test…
Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables.
The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer.
Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
Create a class Mammal and another class WingedAnimal. Make a class Bat that is derived from both the classes as bat is a mammal as well as a winged animal.Make constructor of each class and test your classes by making an object of Bat in main function.

- Write a code for the tracking problem: Consider a tracking program that will track four types of things: Books, Mobiles, Laptop, and Bags. • Implement the Tracking program. • Allow the user to add, modify, and delete Books, Mobiles, Laptop, and Bags. • Allow the user to search for an asset by its serial number.

Next, override (add) the makes Sound() method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don't make sounds!) Note, you'll also need a constructor in each of your subclasses which calls super(name) to initialize the common 'name' member of Animal. Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each.

- NOTE: READ CAREFULLY Design a class named Person and a subclasses named Employee. Make Teacher a subclass of Employee. A Person has a name, address, and e-mail address. An Employee has an office, salary. A Teacher has office hours and a subject they teach. They also have a tenure status. Define the tenure status as a constant. The tenure status is either Senior or Junior, and is represented as an integer, where Senior is equal to 1, and Junior is equal to 2. Each class should have a Default constructor, and a constructor that accepts all arguments. There should be appropriate calls to the superclass within the constructors. Each class should also have getters and setters for each member variable. Each class should have a toString method. Note: You do NOT need to run this in a test program.
