本系统是基于java开发的聊天室。服务端和客户端可以发送和接收消息，由于未写出服务端窗口，聊天记录只会在输出的窗口显示。如果服务器还未启动，客户端不能利用聊天室发消息。若在运行过程中服务器断开，系统会有提示。(This system is a chat room based on java. Both the server and the client can send and receive messages. Since the server window is not written out, the chat record will only be displayed in the output window. If the server has not been started, the client can not use the chat room to send messages. If the server is disconnected during operation, the system will be prompted.)
