Problem 2 In Java you are to implement an employee payroll system. The Acme Gaming company consists of people. Each Person has an id and a lastName. The three types of employees are HourlyWorker, CommissionedWorker, and Intern. In addition to id and lastName an HourlyWorker, will keep track of the numbers of hours worked and the hourly pay rate. For this employee the ComputeSalary () method will compute the regularPay (the first 40 hour) as payRate * hoursWorked. For overtimePay (hours beyond 40) the pay rate will be time and half. The total pay will be the sum of the regularPay and the overtimePay. In addition to id and lastName a CommissionedWorker will keep track of the total amount of sales, and the commission rate. The total pay will be total sales * commission rate. For this employee the ComputeSalary () method will compute the totalPay = totalSales * commissionRate. In addition to id and lastName an Intern will keep track of the weekly pay amount for this employee the ComputeSalary () method will compute the total pay as simply the weekly pay amount. It should be clear that ComputeSalary () is a polymorphic method. Use the DRY principle when designing your classes. Your class diagram might look like in BlueJ: Note that Person is an abstract class. There is one last thing you need to do so that both output loops in P2 () work. You should override the toString method in the Person class. The implementation might look like this: ``` BOverride public String toString() l return (this.id + " " + this.lastName); } ``` You should also override in the other classes. For example, in the HourlyWorker class it might look like: ``` @Override public String toString() { return (super.toString() + " " + this.ComputeSalary()); } ``` Notice the use of super to invoke the tostring method in the superclass Person. Output from your Project5_driver. java should look like this: 101 Smith 563.75 123 Jones 1000.0 120 Wilson 120.0 103 Williams 1113.75 140 Decker 3500.0 129 Brown 105.0 113 Miller 1890.625 150 Davis 3000.0 180 Adams 100.0 119 Murphy 1906.25 ``` static void P2() { ``` ``` List people = new ArrayList<>(); ``` List people = new ArrayList<>(); Person refVarPerson = null; Person refVarPerson = null; // ID Last Hours rate // ID Last Hours rate // ID Last Hours rate // ID Last Hours rate people.add(new CommissionedWerker(123, "Jones", 10000.0, 0.10)); people.add(new CommissionedWerker(123, "Jones", 10000.0, 0.10)); // ID Last weekly stipend // ID Last weekly stipend people.add(new Intern(120, "Wilson", 120.00)); people.add(new Intern(120, "Wilson", 120.00)); people.add(new HqurlyWQcker(103, "Williams", 50, 20.25)); people.add(new HqurlyWQcker(103, "Williams", 50, 20.25)); people.add(new CommissionedWerker(140, "Decker", 35000.0, 0.10)); people.add(new CommissionedWerker(140, "Decker", 35000.0, 0.10)); people.add(new Intern(129, "Brown", 105.00)); people.add(new Intern(129, "Brown", 105.00)); people.add(new HourlyWlacker(113, "Miller", 55, 30.25)); people.add(new HourlyWlacker(113, "Miller", 55, 30.25)); people.add(new Commissi\ellnedWNarker(150, "Davis", 15000.0, 0.20)); people.add(new Commissi\ellnedWNarker(150, "Davis", 15000.0, 0.20)); people.add(new Intern(180, "Adams", 100.00)); people.add(new Intern(180, "Adams", 100.00)); people.add(new HourlyWCcker(119, "Murphy", 55, 30.50)); people.add(new HourlyWCcker(119, "Murphy", 55, 30.50)); for (int i = 0; i < people.size(); i++) { refVarPerson = people.get(i); System.out.println(refVarPerson); } System.out.println(); System.out.println("id Name Salary"); ``` for (Persan refVar : people) // Enhanced for loop (for-each) \{ System.out.printf("\%d \%15s \$\%8.2f\n", refVar.GetId(),refVar.GetLastName(), refVar.ComputeSalary()); \}
