有关多线程和socket问题？？？

[mrlining1]

我在一个多线程的类中有如下代码
....
....
public class ProcessRequest implements Runnable{
....
....
private Socket socket;
private ChatServer server;
private DataInputStream inputStream;
private DataOutputStream outStream;

public ProcessRequest(ChatServer server, Socket socket) throws IOException{
this.socket = socket;
InetAddress inet = socket.getInetAddress();
userIP = inet.getHostAddress();
this.server = server;
outStream = new DataOutputStream(socket.getOutputStream());

// inputStream = new DataInputStream(socket.getInputStream());

}
public void run() {
String accept, cmd;


while (true) {
try {

outStream.writeUTF("hello");

}



} catch (Exception e) {
}
break;
}
}
.......
.....
其中// inputStream = new DataInputStream(socket.getInputStream());
为什么注释掉就好使，将注释去掉，就无法将数据送出。难到inputstream 和outputstream不能同时得到?????或者是因为多线程的问题,是否要使用同步???

对 接受 和发送因该在两个线程中、

当然能同时得到，TCP是双向的，别的地方有问题。

socket连接一旦建立，就可以双向通信了。同意 jimjxr(宝宝猫)

是不是new DataInputStream(InputStream stream)在stream中没有可读数据时阻塞了，new ObjectInputStream(InputStream stream)时是这样的。
