同时链接一个Applet和JFrame？

Question

I have two java classes. One is a JFrame that displays the methods from the applet. I want the TollboothDisplay java to change whenever the Booth applet is ran. Here are both of the programs. TollboothDisplay.java

    package Booth;
/**
 * Write a description of class TollboothDisplay here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
@SuppressWarnings("serial")
public class TollboothDisplay extends JFrame
{
private JLabel count;
private JLabel money;
private Booth myBooth;
    /**
     * Constructor for objects of class TollboothDisplay
     */
    public TollboothDisplay()
    {
        myBooth = new Booth();
        count = new JLabel("Number of Cars: " + myBooth.traffic());
        money = new JLabel("Amount Collected: $" + myBooth.profit());
        getContentPane().add(count,BorderLayout.NORTH);
        getContentPane().add(money,BorderLayout.SOUTH);
        addMouseListener(new click());
        myBooth.add(myBooth);
    }
    public void update()
    {
        count.setText("Number of Cars: " + myBooth.traffic());
        money.setText("Amount Collected: $" + myBooth.profit());
        repaint();
    }
    public void paint(Graphics g)
    {
        paintComponents(g);   
    }
    @SuppressWarnings("deprecation")
    public static void main(String args[])
    {
        TollboothDisplay myDisplay = new TollboothDisplay();
        myDisplay.setSize(200,200);
        myDisplay.show();
        myDisplay.setTitle("Tollbooth Version 1");
    }
    private class click implements MouseListener
    {
        public void mousePressed(MouseEvent e){}
        public void mouseReleased(MouseEvent e){}
        public void mouseEntered(MouseEvent e){}
        public void mouseExited(MouseEvent e){}
        public void mouseClicked(MouseEvent e){
        myBooth.addCar();
        update();}
    }
}

Booth.java

    package Booth;
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
/**
 * Class Booth - write a description of the class here
 * 
 * @author (your name) 
 * @version (a version number)
 */
@SuppressWarnings({ "serial", "unused" })
public class Booth extends Applet implements ActionListener
{
    //Panel panel;
    Label label;
    Button b;
    int countCars;
   public void init()
   {
       //panel= new Panel();
       b=new Button("Add Car");
       label = new Label();
       //add(panel);
       add(b);
       add(label);
       b.addActionListener(this);
       countCars = 0;
    }
    public void actionPerformed(ActionEvent e)
    {   countCars++;
        label.setText(""+countCars);
        validate();
        invalidate();
    }
    public int traffic() {
        return countCars;
    }
    public double profit() {
        double price = countCars * 3.25;
        return price;
    }
    public int addCar() {
        return countCars;
    }
}

Ended up just making an Applet. It was just a lot easier that way. Here it is

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
@SuppressWarnings({ "serial", "unused" })
public class Booth extends Applet implements ActionListener
{
    //Panel panel;
    Label displayCars;
    Label profit;
    Label traffic;
    Label total;
    Button a;
    Button m;
    int countCars;
    int cars;
   public void init()
   {
       //panel= new Panel();
       a = new Button("Cars in line");
       m = new Button("Car passes through");
       displayCars = new Label();
       profit = new Label();
       traffic = new Label();
       total = new Label();
       //add(panel);
       add(a);
       add(m);
       add(displayCars);
       add(profit);
       add(traffic);
       add(total);
       a.addActionListener(this);
       m.addActionListener(this);
       countCars = 0;
       cars = 0;
    }
    public void actionPerformed(ActionEvent e)
    { 
        if (e.getSource() == a)
        {
        countCars++;
        cars++;
        }
        else if (e.getSource() == m)
        {
        countCars--;
        }
        displayCars.setText(" "+countCars);
        profit.setText("Estimated Profit: $" + cars * 3.25);
        traffic.setText("Cars Left in line: " + countCars);
        total.setText("Total Cars: " + cars);
        validate();
        invalidate();
    }
}
