Java Programming

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 company’s employee base:

Programmers:

Lawyers:

Accountants:

   {
       this.name = name;
       baseSalary = 40000;
   }//End of constructor
   //Returns salary
   double getSalary()
   {
       return baseSalary;
   }//End of method
   //Abstract method
   abstract void reportSalary();
}//End of class
//Class Lawyers inherited from Employee
class Lawyers extends Employees
{
   //Instance variable

   //Constructor
   Lawyers(String name, int stock)

       super(name);
       StockOptionsEarned = stock;
   }//End of constructor
   //Overrides salary method
   double getSalary()
   {
       return baseSalary + 30000;
   }//End of method

   }//End of method  
}//End of class
//Class Accounts inherited from Employee
class Accountants extends Employees
{
   //Instance variable
   double parkingAllowanceAmount;
   //Constructor
   Accountants(String name, double par)
   {
       super(name);
       parkingAllowanceAmount = par;
   }//End of constructor
   //Returns parking allowance
   double getParking()
   {
       return parkingAllowanceAmount;
   }//End of method
   //Overrides abstract method
   void reportSalary()
   {
       System.out.println(name + " I am an accountant. I make " + getSalary() + " plus a parking allowance of " + getParking());
   }//End of method
}//End of class
//Class Programmer inherited from Employee
class Programmers extends Employees
{
   //Instance variable
   boolean busPass;
   //Constructor
   Programmers(String name, boolean bp)
   {
       super(name);
       busPass = bp;
   }//End of constructor
   //Overrides salary
   double getSalary()
   {
       return baseSalary + 20000;
   }//End of method
   //Returns buss pass status
   boolean getBusPass()
   {
       return busPass;
   }//End of method
   //Overrides abstract method
   void reportSalary()
   {
       System.out.println(name + " I am a programmer. I make " + getSalary() + " and I " + ((getBusPass())? " get a bus pass.":" do not get a bus pass."));
   }//End of method
}//End of class

//Driver class
public class Salary
{
   //Main method
   public static void main(String ss[])
   {
       //Creates object for programmer
       Programmers pr = new Programmers("Pyari", true);
       Programmers pr1 = new Programmers("Sasmita", false);
       Accountants ac = new Accountants("Mohan", 100.23);
       Lawyers la = new Lawyers("Sahu", 54);
       pr.reportSalary();
       pr1.reportSalary();
       ac.reportSalary();
       la.reportSalary();
   }//End of main method
}//End of class

Output:

Pyari I am a programmer. I make 60000.0 and I get a bus pass.
Sasmita I am a programmer. I make 60000.0 and I do not get a bus pass.
Mohan I am an accountant. I make 40000.0 plus a parking allowance of 100.23
Sahu I am a lawyer. I get 70000.0, and I have 54 shares of stock.
