LabInheritance PDF

This document describes an inheritance lab assignment for a programming class. Students are tasked with creating a program for a law firm that tracks employee salaries using inheritance. There are three types of employees - programmers, lawyers, and accountants - with their own attributes and salary calculations. The program must set up a class hierarchy with an abstract Employee class and subclasses for each type of employee. Employees will have a name and salary attribute, and subclasses will implement a reportSalary() method to print salary details specific to that type.

Inheritance Lab
You are a programmer in the IT department of an important law firm. Your job is to create a program
that will report gross salary amounts and other compensation.

There are three types of employees in your firm:


Programmers
Lawyers
Accountants

Your computer-based solution will use inheritance to reflect the general-to-specific nature of your
employee hierarchy.

Common attributes for all employees are:


Name
Salary
Attributes for specific employee types are:
Lawyers:
Stock options earned (type int)
Accountants
Parking allowance amount (type double)
Programmers:
Bus pass (type boolean)
The three specific classes of employees should extend the abstract Employee class (nobody is a generic
employee) and implement their own reportSalary() method.

The pay schedule is:


o Employees earn the base salary of $40K per year
o Accountants earn the base employee salary per year
o Programmers earn the base employee salary plus $20K per year
o Lawyers earn the base employee salary plus $30K per year

Requirements:

o Each subclass of Employee must implement its own reportSalary() method. The specific
implementations of reportSalary() are limited to a printed line:

System.out.println(I am a lawyer. I get + getSalary() + , and I have +


getOptions() + shares of stock.);

System.out.println(I am an accountant. I make + getSalary() + plus a parking


allowance of + getParking());

System.out.println("I am a programmer. I make " + getSalary() + " and I" +


((getBusPass())?" get a bus pass.":" do not get a bus pass."));

o Salaries for specific types of employees are in addition to the base employee salary.
Raising the base employee salary should automatically raise salaries for all types of
employees (hmmm).
o An object of the Employee class cannot be instantiated because it would be too
general.
o Attribute(s) that belong to a super or sub class should be initialized in the corresponding
class constructor.

Task 1:
Setup a class hierarchy to accurately reflect the relationships in your law firm.

Task 2:
Create a driver program that will create employee objects and report salaries for your companys
employee base:

Programmers: (your name goes here) - No bus pass


Will E. Makit - Bus pass

Lawyers: Ivana Killmen - 11 shares signing bonus


Luke N. Dimm - 0 shares signing bonus
Eileen Dover - 100 shares signing bonus

Accountants: Bill Cheatem - Parking allowance $ 17.00


Joe Kisonyou - Parking allowance $ 45.50
Seymore Butts - Parking allowance $ 2.50
