Create the following classes: Person Class: Create a class called Person with definition as follows. Completing the definitions of the methods is part of this programming assignment. Employec Class: The Employee class extends the Person class and has instance varible hi reDate (since it will hold the hining date of an employee so use Date class). This class will have following three constructors: 1. No argument constructor 2. An argument constructor that receives naree and hi reDate. 3. An argument constructor that receives Emp loyee object. Define the constructors, mutator and accessor methods, and suitably define tostring and equa is methods. SalariedEmployee Class: The SalariedEmployee class extends the Employee class and has instance variable sa a ary. The chass. will have the following three constructors: 1. No argument constructor 2.

Billing Class: Give the definition of class Billing whose objects are tecords for a clinic. A Billing object will contain a Patient object, a Doctor object, and an amount due of type double. Be sure your class has a reasonable complement of constructors, accessor and mutator methods, and suitably defined equals and tostring methods.

At the end print our the total income from the Billing reconds Sample Output The sample output of the main prognam is depicted in the below picture.
