有两种通用解决方案：全服务器和无服务器。如果是基于服务器的解决方案，您的所有客户端都应预先配置服务器的 IP 地址。服务器打开服务器套接字并开始侦听。因此，每个客户端连接到服务器并注册。注册非常简单：服务器只需要客户端的IP即可。现在服务器保存已连接客户端的列表并将该列表发送给每个客户端。为了使peer2peer应用程序每个客户端也打开服务器套接字。当客户端 A 希望连接到客户端 B 时，它只需连接到其套接字。
There are 2 general solutions: server-full and server-less. In case of server based solutions all your clients should be pre-configured with the server's IP address. Server opens server socket and starts listening. So, each client connects to server and registers. The registration is very simple: server just needs the client's IP. Now server holds a list of connected clients and sends the list to each client. To make peer2peer app each client opens server socket too. When client A wishes to connect to client B it just connects to its socket.
You can implement server-less solution. In this case you need some discovery mechanism based for example on broadcasting.

对于大学项目，请阅读一些有关套接字的教程。我相信这也是你的教授对你的期望。以下面为例： http://www.oracle.com/technetwork/java /socket-140484.html

您可以实施无服务器解决方案。在这种情况下，您需要一些基于例如广播的发现机制。
我希望这有帮助。祝你好运。
For university project read some tutorial about sockets. I believe that this is what your professor is expecting from you. Take for example the following: http://www.oracle.com/technetwork/java/socket-140484.html

I hope this helps. Good luck.
