聊天程序小问题

[bbhere]

写的聊天程序，server端运行后有下面错误
Exception in thread "main" java.net.BindException:Address already in use:JVM_Bind
at java.net.PlainSocketImpl.socketBind(Native Method)
at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:331)
at java.net.ServerSocket.bind(ServerSocket.java:318)
at java.net.ServerSocket.<init>(ServerSocket.java.185)
at java.net.ServerSocket.<init>(ServerSocket.java.97)
at Server1.main(Server1.java:7)
小弟初学java，看不懂，请高手指点，告诉小弟该如何修改，不胜感激，代码如下：
import java.net.*;
import java.io.*;
public class Server1
{
public static void main(String[] args) throws IOException
{
ServerSocket ss=new ServerSocket(10000);
Socket s=null;
String toClient;
try{
System.out.println("等待客户端连接");
while(true)
{
s=ss.accept();
String ip=""+s.getInetAddress();
System.out.println("IP:"+ip+"登陆");
try{
new ReceiveClientThread(s);
}catch(Exception e){s.close();} }
}catch(IOException e){System.err.println("Failed to connect");}

}
}
class ReceiveClientThread extends Thread{
private Socket s;
private DataInputStream datain;
private DataOutputStream dataout;
private BufferedReader in;
String toClient;
String fromClient;
public ReceiveClientThread(Socket socket) throws IOException {
s=socket;
datain=new DataInputStream(s.getInputStream());
dataout=new DataOutputStream(s.getOutputStream());
in=new BufferedReader(new InputStreamReader(System.in));
start();}
public void run()
{
try{
while(true){
fromClient=datain.readUTF(); System.out.println("client说:"+fromClient);
if(fromClient.equals("quit"))
{
System.out.println("Client exit");
break;
}
toClient=in.readLine();
dataout.writeUTF(toClient);
}
}catch(Exception e){}
}
}

我再等

[pegasus827]

先刷再关

[bbhere]

我不会用flush阿，谁能帮我把这个程序改一下吗？加分阿，加分阿
在线等

[leon_jiang]

class ReceiveServerThread extends Thread{
private Socket s;
private DataInputStream datain;
private DataOutputStream dataout;
private BufferedReader in;
String toServer;
String fromServer;
public ReceiveServerThread(Socket socket) throws IOException {
s=socket;
datain=new DataInputStream(s.getInputStream());
dataout=new DataOutputStream(s.getOutputStream());
in=new BufferedReader(new InputStreamReader(System.in));
start();}
public void run()
{
try{
while(true){
fromServer=datain.readUTF();
System.out.println("server说:"+fromServer);
if(fromServer.equals("quit"))
{
System.out.println("Server exit");
break;
}
toServer=in.readLine();
dataout.writeUTF(toServer);
}
}catch(Exception e){}
finally
{
dataout.flush();
in.flush();
datain.flush();dataout.close();in.close();datain.close();
}
}
}

谢谢楼上大哥，不过还是不行，编译出一下错误
Server1.java:58:cannot resolve symbol
symbol:method flush()
location:class java.io.BufferedReader
in.flush();
^

Server1.java:59:cannot resolve symbol
symbol:method flush()
location:class java.io.DataInputStream
datain.flush();
^

这是怎么回事？

[mofeir]

换一个端口。

[bbhere]

哦，解决了，不过运行client时，又出来问题
Exception in thread "main" java.lang.OutOfMemoryError
我查了API也没看懂是什么意思，楼上大哥能再给讲讲么？
import java.net.*;
import java.io.*;
public class Client1
{
public static void main(String[] args) throws IOException
{
Socket s=null;
String toServer;
try{
s=new Socket("192.0.0.168",6666); System.out.println("you have connected the server");
while(true)
{ try{
new ReceiveServerThread(s);
}catch(Exception e){s.close();} }
}catch(IOException e){System.err.println("Failed to connect");}

}
}
class ReceiveServerThread extends Thread{
private Socket s;
private DataInputStream datain;
private DataOutputStream dataout;
private BufferedReader in;
String toServer;
String fromServer;
public ReceiveServerThread(Socket socket) throws IOException {
s=socket;
datain=new DataInputStream(s.getInputStream());
dataout=new DataOutputStream(s.getOutputStream());
in=new BufferedReader(new InputStreamReader(System.in));
start();}
public void run()
{
try{
while(true){
fromServer=datain.readUTF();
System.out.println("server说:"+fromServer);
if(fromServer.equals("quit"))
{
System.out.println("Server exit");
break;
}
toServer=in.readLine();
dataout.writeUTF(toServer);
}
}catch(Exception e){}
}
}

数据传递完后有关闭你的IO流，而且要flush一下

[jixingzhong]

刷新一下

[bbhere]

哦，关闭我会，就datain.close();dataout.close();等等
flush()怎么用，先关闭还是先刷新？请楼上两位给我讲讲，谢谢阿

[bbhere]

我等

[liudazhong]

看不出来

[bbhere]

出于对知识的不懈追求，我还等

[hifan]

.flush(); //flush the buffer, send message to the destination
.close();

then:
= null;

我写的最基本的聊天程序，400行代码。

[bbhere]

急啊，我还等
各位帮忙啊

[bbhere]

是这个问题太简单了么？
等

[bbhere]

谢谢楼上大哥，不过你得客户端用的是udp，我还不懂
呵呵
有没有和我这个差不多的？
