Question
Here is a computer program that I have been unable to properly complete. The requirements are very specific. The output must match the samlple session at the end of the problem. The homework problem and its parameters are copied below:
The file must be called <Payroll.java> (driver program)
Employee.java
Hourly.java (which extends employee)
Salaried.java (which extends employee)
SalariedPlusCommission.java (which extends Salaried)
Ensure you include ALL files required to make your program compile and run.
I would like to see your .java files only.
Proper coding conventions required the first letter of the class start with a capital
letter and the first letter of each additional word start with a capital letter.
Overall Requirements
Write an employee payroll program that uses polymorphism to calculate and print the
weekly payroll for your company. There are three types of employees ? hourly,
salaried, and salaried plus commission. Each type of employee gets paid using a
different formula. But for all employee types, if the calculated paycheck exceeds
$1000, the actual paycheck must be decreased to $1000.
Use this class hierarchy:
Use the public access modifier for the toString method in the Employee class and
the load method in the Employee, Hourly, Salaried, and SalariedPlusCommission
classes.
Employee.java class
Instance variables:
name
social security number
birthday month
birthday week
load method :
Prompts the user for instance-variable values and loads the entries.
toString method:
Returns a string that shows the employee
Explanation / Answer
Employee.java
package chegg;
import java.util.Calendar;
import java.util.Date;
import java.util.Scanner;
public abstract class Employee {
private String name;
private String socialSecurityNumber;
private int birthdayMonth;
private int birthdayWeek;
@SuppressWarnings("resource")
public Employee() {
Scanner input = new Scanner(System.in);
System.out.println("Please Enter Name of the Employee: ");
this.name = input.next();
System.out.println("Please Enter Social Security of the Employee: ");
this.socialSecurityNumber = input.next();
System.out
.println("Please Enter Birthday Month of the Employee(1 - 12): ");
this.birthdayMonth = input.nextInt();
System.out
.println("Please Enter Birthday Week of the Employee(1 - 4): ");
this.birthdayWeek = input.nextInt();
}
@Override
public String toString() {
return "PAYCHECK REPORT: " + "employee: " + name + " "
+ "social security number: " + socialSecurityNumber + " "
+ "paycheck: " + (getEarnings() + getBonus()) + " ";
}
public abstract double getEarnings();

// As per assumption

int getCurrentWeek = cal.get(Calendar.DAY_OF_WEEK_IN_MONTH);
// As per assumption

Hourly.java

}
Salaried.java
package chegg;

}
@Override

return weeklySalary;
}
}
SalariedPlusCommission.java
package chegg;
import java.util.Scanner;

private int salesDuringPastWeek;
private double commissionRate;
@SuppressWarnings("resource")
public SalariedPlusCommission() {

this.salesDuringPastWeek = input.nextInt();
System.out
.println("Please Enter Commission Rate of Salaried Employee: ");
this.commissionRate = input.nextDouble();
}
@Override
public double getEarnings() {
return super.getEarnings() + salesDuringPastWeek * commissionRate;
}
}
PayRoll.java
package chegg;
import java.util.Scanner;
public class PayRoll {
@SuppressWarnings("resource")
public static void main(String arg[]) {
Scanner input = new Scanner(System.in);
System.out.println("Please Enter the number of Employees: ");
int numOfEmployees = input.nextInt();
for (int employeeCount = 0; employeeCount < numOfEmployees; employeeCount++) {
System.out.println("PROFILE FOR EMPLOYEE #" + (employeeCount + 1));
System.out
.println("type Hourly(1), Salaried(2), Salaried plus Commission(3)");
System.out.print("Enter 1, 2, or 3 ==> ");
int employeeType = input.nextInt();
switch (employeeType) {
case 1:
Hourly hourlyEmployee = new Hourly();
System.out.println(hourlyEmployee);
break;
case 2:
Salaried salariedEmployee = new Salaried();
System.out.println(salariedEmployee);
break;
case 3:
SalariedPlusCommission salariedPlusCommissionEmployee = new SalariedPlusCommission();
System.out.println(salariedPlusCommissionEmployee);
break;
default:
System.out.println("JUNK VALUE TRY 1 or 2 or 3");
break;
}
}
}
}
Note : change month and week to calender method after testing the sample
