Program Plan:

Filename: Billing.java

• • Define the “Billing.java” class.
• • Declare the required variables.
• • Define the default constructor, and constructor for the class.
• • Define the accessor and mutator methods.
• • Define the “writeOutput” method.
  • ○ Call the “writeOutput” method with different doctor and patient objects.
• • Define the “equals” method.
  • ○ Return Boolean value.

Filename: Doctor.java

• • Define the “Doctor.java” class which extends from the “Person” class.
• • Declare the required variables.
• • Define the constructor for the class.
• • Define the accessor and mutator methods.
• • Define the “writeOutput” method.
  • ○ Display the doctor name, specialization, and visit fee on the output screen.
• • Define the “equals” method.
  • ○ Return Boolean value.

Filename: Patient.java

• • Define the “Patient.java” class which extends from the “Person” class.
• • Declare the required variables.
• • Define the default constructor, and constructor for the class.
• • Define the accessor and mutator methods.
• • Define the “writeOutput” method.
  • ○ Display the patient name, and ID on the output screen.
• • Define the “equals” method.
  • ○ Return Boolean value.

Filename: Demo.java

• • Define main function.
  • ○ Create the objects for “Doctor”, “Patient”, and “Billing” classes and pass the input value to the respective methods.
  • ○ Call the “writeOutput” method with “Billing” object “b1”.
  • ○ Call the “writeOutput” method with “Billing” object “b2”.
  • ○ Calculate the visit fees for first and second doctors.
  • ○ Add the fees and stored it in a “total” variable.
  • ○ Display the total amount.
  • ○ Compare the “b1” and “b2” values then print Boolean result.
