Problem 2: Employee (10 points) (Software Design) Create an abstract class that represents an Employee and contains abstract method payment. Create concrete classes: SalaryEmployee, CommissionEmployee, HourlyEmployee which extend the Employee class and implements that abstract method. A Salary Employee has a salary, a Commision Employee has a commission rate and total sales, and Hourly Employee as an hourly rate and hours worked Software Architecture: The Employee class is the abstract super class and must be instantiated by one of its concrete subclasses: SalaryEmployee, CommissionEmployee, or HourlyEmployee, which extends it.

//Java Program

abstract class Employee{
   private String name;
   public Employee(String name) {
       this.name=name;
   }
   public String toString() {
       return name;
   }
   abstract public double getpayment();
}
class SalaryEmployee extends Employee{
private double salary;
   public SalaryEmployee(String name,double salary) {
       super(name);
       this.salary = salary;
   }

   @Override
   public double getpayment() {
       return salary/24;
      
   }
   public String toString() {
       return super.toString()+" salary:$"+salary;
   }
  
}
class CommissionEmployee extends Employee{
private double commissionRate;
