[Solved]Create Program Consists Following Classes Abstract Class Employeel O Three Instance Vari Q37170064
Create a program that consists of the following classes: a. Abstract class Employeel that has . o three instance variablesoftypeStrings Empere . firstName lastName social Security Number o set and get methods for each instance variable o a constructor that takes three string arguments to be assigned to the instance variables o a method toString that returns a string representation for values of the instance variables toString that string an abstract method earnings that returns a double value o Class Employee2 that extends the abstract class Employeel and has: an instance variable weeklySalary of type double set and get methods for weeklySalary instance variable a constructor that takes one double argument and three string arguments to be assigned to the instance variables o o o o an implementation of the abstract method earnings that has been inherited from the class Employeel. The earnings method should calculate the earning based on the weeklySalary o a method toString that returns a string representation for values of the instance variables Class Employee3 that extends the abstract class Employeel and has: o an instance variable grossSales of type double o an instance variable commissionRate of type double o set and get methods for grossSales and commissionRate instance variables o a constructor that takes two double arguments and three string arguments to be assigned to the instance variables o an implementation of the abstract method earnings that has been inherited from the class Employeel. The earnings method should calculate the earning based on commissionRate and grossSales. o a method toString that returns a string representation for values of the instance Comnivariables Class Employee4 that extends the abstract class Employeel and has: an instance variable wage of type double an instance variable hours of type double set and get methods for wage and hours instance variables a constructor that takes two double arguments and three string arguments to be assigned to the instance variables o o o o o an implementation of the abstract method earnings that has been inherited from the class Employeel.
