Define two classes, Patient and Billing, whose objects are records for a clinic. A Patient record has the patient$$s name $($defined in the class Person$)$ and identification number $($use the type String$).$ A Billing object will contain a Patient object and a Doctor object. Give your classes a reasonable complement of constructors and accessor methods, and an equals method as well. First write a driver program to test all your methods, then write a test program that creates at least two patients, at least two doctors, and at least two Billing records and then displays the total income from the Billing records. Below is what I have so far but I get an error code in the doctor class about the super display. Could someone fix what I have wrong and run the program to work properly?
