聊天程序小问题

Question

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){}
}
}

Answer 1

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){}
}
}

Answer 2

数据传递完后有关闭你的IO流，而且要flush一下

Answer 3

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

Answer 4

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

Answer 5

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();
                   }
}
}

Answer 6

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？

Answer 7

.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。

Answer 9

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？
