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:");

   pass=sc.nextInt();

}

void display(){

System.out.println("No. of wheels:"+wheels+"\nSpeed:"+speed+"km/hr\nNo. of passengers:"+pass);

}

}

class Truck extends Vehicle{

 double limit;

 void input()  {

    Scanner sc=new Scanner(System.in);

System.out.println("Enter the Truck's details:\nNo. of wheels:");

    wheels=sc.nextInt();

System.out.println("Speed of Truck(Km/hr):");

    speed=sc.nextDouble();

System.out.println("Load limit:");

    limit=sc.nextDouble();

}

 void display()  {

System.out.println("No. of wheels:"+wheels+"\nSpeed:"+speed+"km/hr\nLoad limit:"+limit);}

}

class test{

public static void main(String ts7[]){

Car ob1= new Car();

Truck ob2=new Truck();

ob1.input();

ob2.input();

if(ob1.speed>ob2.speed)

System.out.println("Car is faster");

else

System.out.println("Truck is faster");

ob1.display();

ob2.display();

}

}
