烦恼...基础的都不会..
将线程用在socket上面，老是实现不了，非常不解...请各位高手指点一下。

首先谢谢看完的朋友，再多谢回答的朋友，这个线程和socket自己学着感觉问题很多，而且自己动手写的没有运行到过..搞到我人都烦了.所以请高手指点下.

[解决办法]
可以这样创建线程么？
[解决办法]
...你建程的目的是什么？你什么要在你的里那 run方法？
[解决办法]
这样写线程好像不对吧，第一次看到这样写，我觉得可以写成匿名内部类的形式，如下：
new Thread(new Runnable(){
if (ss != null) {
while (true) {
try {
s = ss.accept();
new Thread(run2(s)).start();
} catch (IOException e) {
// TODO Auto-generated catch block
System.exit(0);
}
}
}
}).start();
只有启动线程就没有问题了
[解决办法]
线程基础的就两种方法，一个是实现RUNNABLE借口的类，在THREAD()中引用。
另一个是extends thread一个类,然后直接START。
改一下写法大概就行了。
