All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Modify the Auto class to include an instance variable for the license plate number. Implement the constructor so that an Auto can be constructed with a VIN and a license plate number. Override the getID() method to return the id of the auto as shown in this format: VIN=1234567890,plate=ABC123 (without any spaces). ** Represents an automobile.*/public class Auto // TODO: Inherit from Vehicle{ // TODO: Declare instance variables public Auto(String vin, String plate) { // TODO: Complete the constructor } // TODO: implement the getID() method for autos}

Write a complete program for the description given below. Consider a Billing class that implements an interface Payable having a method getTotalPayment Amount(). Besides this, you have a Doctor class with private instance variables (docID, docName, and docFee) and a public getDoc() method, Patient class with private instance variables (pName, pID. pDisease), Medicine class with private instance variables (medID, medName, medQty, medPrice), and Medical Test class with private instance variables (testID, testName, testPrice). Each of these classes has the toString() method to display the information of its object. The Billing class is having "Has A" relationship with the other four classes (Doctor, Patient, Medicine, and MedicalTest) mentioned above. The getPayment Amount() method of Billing class returns the total billing amount that includes doc fee, medicine cost, and medical test fee that a patient has to pay.
