Design а Vehicle Clаss with the fоllоwing prоperties: Privаte Data Members: String model String color double price Constructors: (20) Default constructor (assigns default values) (5) Parameterized constructor that assigns all values to all members (5) Copy constructor (takes another Vehicle object and copies its data to the newly created object) (10) Methods: (45) Write Public getters and setters for all attributes as needed. (Not required by the assignment, your need will drive it) void displayDetails() → prints the vehicle details. (10) void updateInfo(double newPrice) → updates price. (5) void updateInfo(double newPrice, String Color) → updates both price and color. (5) void updateInfo(double newPrice, String Color, String model) → updates all price, model, and color. (5) double comparePrice(Vehicle other)→ compare the price of this vehicle with the other vehicle passed and return the difference amount. (10) The VehicleTester class should have a main function that will test the functionality by (35) Creating three Vehicle Objects v1, v2 and v3 using: (10) Default constructor (v1) Parameterized constructor (v2) Copy constructor (v3, which isa copy of v2) Use updateInfo()function to set all the member variables of vehicle v1. (10) Call printVehicle() Methods for all the objects. (5) Use comparePrice()function to compare two objects. (v1 and v2) (10)
