JAVA聊天室 客户端 和 服务器 完整代码CS模式的QQ这是服务器:ChatServer.javaimport java.net.*;
import java.io.*;
public class ChatServer
{
final static int thePort=8189;
ServerSocket theServer;
ChatHandler[] chatters;
int numbers=0;
public static void main(String args[])
{
ChatServer app=new ChatServer();
app.run();
}
public ChatServer()
{
try
{
theServer=new ServerSocket(thePort);
chatters=new ChatHandler[10];
}
catch(IOException io){}
}
public void run()
{
try
{
System.out.println("服务器已经建立！");
while(numbers10)
{
Socket theSocket=theServer.accept();
ChatHandler chatHandler=new ChatHandler(theSocket,this);
chatters[numbers]=chatHandler;
numbers++;
}
}catch(IOException io){}
}
public synchronized void removeConnectionList(ChatHandler c)
{
int index=0;
for(int i=0;i=numbers-1;i++)
if(chatters[i]==c)index=i;
for(int i=index;inumbers-1;i++)
chatters[i]=chatters[i+1];
chatters[numbers-1]=null;
numbers--;
}
public synchronized String returnUsernameList()
{
String line="";
for(int i=0;i=numbers-1;i++)
line=line+chatters[i].user+":";
return line;
}
public void broadcastMessage(String line)
{
System.out.println("发布信息:"+line);
for(int i=0;i=numbers-1;i++)
chatters[i].sendMessage(line);
}
