Chapter 8, Problem 3P
Create a base class called Vehicle that has the manufacturer's name (type string), number of cylinders in the engine (type int), and owner (type Person given in Listing 8.1). Then create a class called Truck that is derived from Vehicle and has additional properties: the load capacity in tons (type double, since it may contain a fractional part) and towing capacity in tons (type double). Give your classes a reasonable complement of constructors and accessor methods, and an equals method as well. Write a driver program (no pun intended) that tests all your methods.

Problem: Create a base class called Vehicle that has the manufacturer’s name (typeString), number of cylinders in the engine (type int), and the owner (type Person). Use thePerson class developed this semester. Create a class automobile that is derived fromVehicle and has additional properties: number of passengers (type int) and weight in tons(type double). Create a class Truck which is derived from Vehicle and has additionalproperties: the load capacity in tons (type double, since it may contain a fractional part)and towing capacity in tons (type double). The classes should have:• Two constructors, a default and an overloaded constructor• All appropriate accessor and mutator methods (getters and setters).• An ‘equals’ method (must conform to the Person example and the Object class ).• A ‘toString’ method• A ‘copy’ constructor• A ‘clone’ method• A ‘finalize’ method
Write a driver (client/test) class that tests ALL the methods. Be sure to invoke each of the constructors, and ALL…
Take the following code snippets (see below) and put them into a class called Employee.
Then create two concrete (non-abstract) classes: Cashier and Supervisor
Set the base salary of cashiers to be $30,000. Set the base salaries of supervisors to be $60,000. (use their constructors to do this).
Create different methods for getMontlySalary() for the Cashier and Supervisor classes.
a) for the Cashier class, just divide the basic salary by 12 to get the monthly.
b) for the Supervisor class, also add a 10% bonus. So a supervisor before any
raises would earn $5500 per month. (60,000/12 + 10%)
Create an employee tester class. Add an array of 10 employees. put 8 cashiers and 2 supervisors into the array. Print out the complete records of all 10 employees using a for loop. (Hint: Overload the toString() on all Employee class).
abstract class Employee {private String name, address;
private int basicSalary;public String getName(){ return name; }public String getAddress(){ return address;…
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…
