我的任务
分享如何将小程序加入到WEB页中
这段是小程序，显示时间的
import java.awt.*;
import java.util.*;
public class Watch extends javax.swing.JApplet
{
private Color butterscotch = new Color(255, 204, 102);
private String lastTime = "";
public void init()
{
setBackground(Color.black);
}
public void paint(Graphics screen)
{
Graphics2D screen2D = (Graphics2D)screen;
Font type = new Font("Monospaced", Font.BOLD, 20);
screen2D.setFont(type);
GregorianCalendar day = new GregorianCalendar();
String time = day.getTime().toString();
screen2D.setColor(Color.black);
screen2D.drawString(lastTime, 5, 25);
screen2D.setColor(butterscotch);
screen2D.drawString(time, 5, 25);
try
{
Thread.sleep(1000);
}
catch (InterruptedException e)
{
//do nothing
}
lastTime = time;
repaint();
}
}
已编译生成Watch.class
这段是html源码
<html>
<head>
<title>Watch Applet</tilte>
</head>
<body>
<applet code="Watch.class" height="50" width="345">
This program requires a Java-enabled browser.
</applet>
</body>
</html>
为什么我打开html却没有任何东西
是不是漏了什么

在"APPLET"标签中指定的宽度和高度一定要比小应用程序的绘图或打印的位置大，否则你在屏幕上就不会看到它了。

applet实在是很麻烦.路径很关键.看看是不是没有把CLASS放当前目录.如果没有放,要把class加上相对路径,要不它可找不着.
