Write a program in java for the following scenario and write a DriverQ class to test your construction: i) Create a class Vehicle which has the following members: Member Variables: • vehicleNumber • ownerName • mulkiaAmt • insuranceAmt Member Methods: A constructor to initialize the vehicleNumber, ownerName, mulkiaAmt and insuranceAmt. An abstract method calcDiscount() to calculate and return the discount amount. An abstract method calcTotalAmt() to calculate and return the amount to be paid. A display( ) method to display the details of the vehicle. ii)Create a subclass PetrolVehicle which is inherited from Vehicle class and has the following details: Member Variables: • serviceCharges Member Methods: • A constructor which will invoke the super class constructor and initialize serviceCharges. • Implement the calcDiscount() method to calculate the discount as, Service Charges Discount 0- 50 1.000 50 - 75 2.000 75 - 90 3.000 90 - 100 4.000 Implement the calcTotalAmt() method to calculate the total amount as, totalAmt =(mulkiaAmt + insuranceAmt + serviceCharges) - discount A method display() to display all the details of the vehicle. iii) Create a driver class named DriverQ which contains the main method. Create objects as follows, PetrolVehicle ("90335MR", “Hashim", 21.0, 45.0, 10.0) Print details of the PetrolVehicle objects.

OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career. 

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
