import java.awt.*;
import java.applet.*;
import java.net.*;
import java.awt.event.*;

public class Lucky52 extends Applet implement ActionListener
{
Panel pNorth=new Panel();
PicPanel pCenter=new PicPanel;
Panel pBottom=new Panel();
TextField txField=new TextField(10);
Label label=new Label("请输入你对商品价格的估计:");
private int nprice=1100;

public Lucky()
{
super();
this.setLayout(new BorderLayout());
pNorth.add(label);
pNorth.add(txField);
add(pNorth,BorderLayout.NORTH);
add(pcenter,BorderLayout.CENTER);
Button btStart=new Button("开始游戏");
Button btOK=new Button("确定");
Button btCancel=new Button("取消");
btStart.setActionCommand("start");
btStart.addActionListener(this);
btOK.setActionCommand("OK");
btOK.addActionListener(this);
btCancel.addActionCommand(&q

这样基本可以：
import java.awt.*;
import java.applet.*;
import java.net.*;
import java.awt.event.*;

import javax.swing.JOptionPane;

public class Lucky52 extends Applet implements ActionListener
{
Panel pNorth=new Panel();
PicPanel pCenter=new PicPanel();
Panel pBottom=new Panel();
TextField txField=new TextField(10);
Label label=new Label("请输入你对商品价格的估计:");
private int nprice=1100;
public Lucky52()
{
super();
this.setLayout(new BorderLayout());
pNorth.add(label);
pCenter.add(txField);
add(pNorth,BorderLayout.NORTH);
add(pCenter,BorderLayout.CENTER);
Button btStart=new Button("开始游戏");
Button btOK=new Button("确定");
Button btCancel=new Button("取消");
btStart.setActionCommand("start");
btStart.addActionListener(this);
btOK.setActionCommand("OK");
btOK.addActionLi
