Create a class Employee, which has three private class variables (Name, Address, PhoneNumber), access methods to get and set each of these properties, and two constructors (one 0-argument constructor and the second setting property values to specific values passed to the constructor).
Create a class SalaryEmployee, which extends Employee and adds one more property (Salary) with proper set and get methods. Add one more method ByWeeklyPay of type double.
Create a class HourlyEmployee, which extends Employee and adds two more properties (HourWage and HoursWorked) with relevant get and set methods. Add one more getPayAmount method.
Create a class UseEmployee, which will instantiate objects of each of the classes above (Employee, SalaryEmployee, HourlyEmployee) with particular values (take any values of the proper data type) and display the information on all properties of an Employee object created, a SalaryEmployee object created, and an HourlyEmployee object created.
Compile, run, and check the results. Submit the following:
