Write a program to create a class named Vehicle having protected instance variables regnNumber, speed, color, ownerName and a method showData() to show "This is a vehicle class". Inherit the Vehicle class into subclasses named Bus and Car having individual private instance variables routeNumber in Bus and manufacturerName in Car and both of them having showData() method showing all details of Bus and Car respectively with content of the super class’s showData ( ) method.

public class Vehicles 
{
    protected String regnNumber, color, ownerName;
    protected int speed;
    MyOwnVehicles(String regno,String c,String owner,int sp)
    {
        regnNumber=regno;
        color=c;
        ownerName=owner;
        speed=sp;
    }
    public void showData() 
	{
        System.out.println("This is a Vehicle Class");
    }
}

class Bus extends Vehicles 
{
    private int routeNumber;

    Bus(String regno, String c, String owner, int sp, int route) 
	{
        super(regno, c, owner, sp);
        routeNumber = route;
    }

    public void showData() 
	{
        super.showData();
        System.out.println("Reg no: " + regnNumber);
        System.out.println("Color: " + color);
        System.out.println("Owner: " + ownerName);
        System.out.println("Speed: " + speed);
        System.out.println("Route: " + routeNumber);
    }
