Question

Create a super class named Vehicle, which has the following attributes: VIN, engine size, Year, Speed. Check

Add a subclass named Car, which has the following additional attributes: Wheel size, Model, Miles (OOD). Check

Add another subclass to the vehicle superclass named Boat which has the following additional attributes: Hours, Gas type, Type (Fishing Boat, Deck boat, bowrider boat), and Check

Write a method named DisplayInfo() in your main to display the information of the Vehicle. In this method print all the features of the vehicle.

Add a method in each class to estimate the price of the vehicle subclasses base on some factors of each type. And call this method from the method DisplayInfo().

In the main method create three objects one of type Vehicle, the second of type Cars, and the third of type Boat.

I have the classes and variables made. How would i create the object (i know how to create) and pass this information to the display info.

Java language

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
