public static void main(String[] args) {
try
{
Thread t1=new Sender();
class Sender extends Thread
{
PipedOutputStream out=new PipedOutputStream();
public PipedOutputStream getPipedOutputStream()
{
return out;
}
t1不能调用getPipedOutputStream()方法，纳闷ing!,谁能告诉我为什么呀，该怎么解决，在线等待
网友回复:你t1就没调什么啊
网友回复:你这个是什么程序...能不能帖全点

网友回复:书写很差呀.楼主要注重一下..
网友回复:同意3楼，呵呵
网友回复:基本技术需要加强啊!!
