编译后，出现14个错误，我修改了7个，还有7个不明白是什么原因，想高手给分析一下。

其实我是按书来打出来的
其运行是在HTML上加上<applet code = .....>，然后通过HTML页面打开来看的
但是在编译的时候，却出现错误，我不明白个中道理，想请高手给分析一下，为什么会出现这样的错误。
程序如下：

import java.applet.Applet.*;
import java.awt.*;

public class TextRunnable extends Applet implements Runnable
{
Label prompt1 = new Label("子线程1");
Label prompt2 = new Label("子线程2");
TextField threadfirst = new TextField(25);
TextField threadsecond = new TextField(25);
Thread thread1,thread2;
int count1;
int count2;

public void init()
{
add(prompt1);
add(prompt2);
add(threadfirst);
add(threadsecond);
}

public void start()
{
Thread thread1 = new Thread(this,"FirstThread");
Thread thread2 = new Thread(this,"SecondThread");
thread1.start();
thread2.start();
}

public void run()
{
String currentRunning;
while (true)
{
try
{
Thread.sleep((int)(Math.random()*100));
}
catch (InterruptedException e)
{
}
currentRunning = Thread.currentThread().getName();
if (currentRunning.equals("FirstThread"))
{
count1++;
threadfirst.setText("线程1第"+count1+"次被调度");
}
else if (currentRunning.equals("SecondThread"))
{
count2++;
threadsecond.setText("线程2第"+count2+"次被调度");
}
}
}
}

你的编译错误信息呢？

能帮我看下是什么原因吗？？
非常希望你能授我以渔。。。。。。。。

[bitiliu]

呵呵，这个我可以告诉你！
程序的第一行改为：
import java.applet.*;
就可以了！

[hujiaboy]

import java.applet.Applet.*;
===>
import java.applet.*;

晕

[candy811114]

1个地方就产生这么多错误啊？？
好象涉及到applet的都出现错误了啦。。。

[candy811114]

感谢上面各位老大了

[GaryZhu]

import java.applet.Applet;

[kingdoom]

用JB OR ECLIPSE 的话 一些问题他会给你提示，你可以先用 jc 错误了后先上eclipse如果有什么不懂得在问吧

[laughsmile]

强烈建议使用eclipse来进行java开发,一看编译器的调试信息,基本的错误都一清二楚了:)
