Objectives

• Implement interface and inheritance
• Implement polymorphism

Prelab

• Read chapter 9 - Inherintance and interfaces
• Review lecture notes on inheritance

Payroll System Using Inheritance and Polymorphism

1. Implement an interface called EmployeeInfo with the following constant variables:

• FACULTY_MONTHLY_SALARY = 5000.00
• STAFF_MONTHLY_HOURS_WORKED = 150

2. Implement an abstract class Employee with the following requirements:

• Attributes
• last name (String)
• first name (String)
• ID number (String)
• Sex - M or F
• Birth date - Use the Calendar Java class to create a date object
• Default argument constructor and argument constructors.
• Public methods
• toString - returning a string with the following format:
  ID Employee number :_________
  Employee name: __________
  Birth date: _______
• mutators and accessors
• abstract method monthlyEarning that returns the monthly earning.

3. Implement a class called Staff extending from the class Employee with the following requirements:

• Attribute
• Hourly rate
• Default argument and argument contructors
• Public methods
• get and set
• The method Earning returns monthly salary (hourly rate times 160)
• toString - returning a string with the following format:
  ID Employee number :_________
  Employee name: __________
  Birth date: _______
  Full Time
  Monthly Salary: _________

Implelment a class Education with the following requirements:

• Attributes
• Degree (MS or PhD )
• Major (Engineering, Chemistry, English, etc ... )
• Research (number of researches)
• Default argument and argument constructors.
• Public methods
• get and set

Implement a class Faculty extending from the class Employee with the following requirements:

• Attributes
• Level (Use enum Java)
  "AS": assistant professor
  "AO": associate professor
  "FU": professor
• Education object
• Default argument and argument constructor
• Public methods
• mutators and accessors
• The method monthlyEarning returns monthly salary based on the faculty's level.
  AS - faculty monthly salary
  AO - 1.5 times faculty monthly salary
  FU - 2.0 times faculty monthly salary
• toString - returning a string with the following format:
  ID Employee number :_________
  Employee name: __________
  Birth date: _______
  XXXXX Professor where  XXXXX can be Assistant, Associate or Full
  Monthly Salary: _________

Implement a class called Partime extending from the class Staff with the following requirements:

• Attributes
• Hours worked per week
• Default argument and argument constructors
• Public methods
• mutators and accessors
• The method monthlyEarning returns monthly salary . The monthly salary is equal to hourly rate times the hours worked in four weeks.
• toString - returning a string with the following format:
  ID Employee number :_________
  Employee name: __________
  Birth date: _______
  Hours works per month: ______
  Monthly Salary: _________

mplement a test driver program that creates a one-dimensional array of class Employee to store the objects Staff, Faculty and Partime.

Using polymorphism, display the following outputs:

a. Employee information using the method toString

• Staff
• Faculty
• Part-time

b. Total monthly salary for all the part-time staff .
c. Total monthly salary for all employees.
d. Display all employee information ascending by employee id using interface Comparer
e. Display all employee information descending by last name using interface Comparable
f. Duplicate a faculty object using clone. Verify the duplication.
