Question

Implement an abstract class Vehicle and concrete subclasses Car and Truck. A vehicle has a position on the screen. Write methods draw that draw cars and trucks as follows;Then write a method randomVehicle that randomly generates Vehicle references, with an equal probability for constructing cars and trucks, with random positions. Call it 10 times and draw all of them.;Use the following class as your main class;import javax.swing.JComponent;import javax.swing.JFrame;/**;This program draws cars and trucks in random order.;*/;public class RandomVehicleViewer;public static void main(String args[]);JFrame frame = new JFrame();final int FRAME_WIDTH = 600;final int FRAME_HEIGHT = 600;frame.setSize(FRAME_WIDTH, FRAME_HEIGHT);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);JComponent component = new RandomVehicleComponent();frame.add(component);frame.setVisible(true);You need to supply the following classes in your solution;RandomVehicleComponent;Car;Truck;Use the following class in your solution;import java.awt.Graphics2D;/**;This class represents a vehicle.;*/;public abstract class Vehicle;private int xleft;private int ytop;/**;Construct a Vehicle object.;*/;public Vehicle();xleft = 0;ytop = 0;/**;Draw the specified vehicle.;@param g2 the graphics context;*/;public abstract void draw(Graphics2D g2);/**;Set the location of the vehicle.;@param x the x coordinate;@param y the y coordinate;*/;public void setLocation(int x, int y);xleft = x;ytop = y;/**;Returns the x coordinate of the left-top corner of the vehicle;@return the x coordinate;*/;public int getX();return xleft;/**;Returns the y coordinate of the left-top corner of the vehicle;@return the y coordinate;*/;public int getY();return ytop;public abstract int getHeight();public abstract int getWidth()
