Question: Create a base class called “Vehicle” that stores number of wheels and speed. Create the following derived classes

Question: Create a base class called “Vehicle” that stores number of wheels and speed. Create the following derived classes:  Ø “Car” that inherits “Vehicle” and also stores number of passengers.  Ø “Truck” that inherits “Vehicle” and also stores the load limit.  Write a main() function to create objects of these classes and display all the information about Car and Truck. Also, compare the speed of the two vehicles, Car and Truck and display “faster” or “slower” if Car is faster or slower than Truck. import java.util.*; class Vehicle{   int wheels;   double speed; } class Car extends Vehicle{   int pass;   void input(){    Scanner sc=new Scanner(System.in); System.out.println("Enter the car's details:\nNo. of wheels:");    wheels=sc.nextInt(); System.out.println("Speed of Car(Km/hr):");    speed=sc.nextDouble(); System.out.println("No. of passengers:");   ...

Question: Develop an abstract class “GeometricObject” which will have two variables colourand weight. It would have constructor function for setting the colour as “white” and the weight as 1.0 as default values. The class should have methods getColour() and getWeight() to return the colour and weight values to the caller. The class should have two abstract methods findArea() and findCircumference(). Write a subclass for “GeometricObject” called “Triangle” which will be able to calculate area and circumference for a triangle.
