java实现聊天室功能(包含全部代码,有界面)

1、服务器端代码：import .*;import java.io.*;import java.util.*;import java.util.concurrent.*;import javax.swing.*;public class Serverprivate static final int PORT=6666;G_Menu gm=new G_Menu();private ServerSocket server;public ArrayList list;public static String user;public static ArrayList list1=new A
