有没有一种方法可以唯一地标识套接字？

Question

I'm trying to implement a simple Client/Server program in Java (mainly through the multi Client and Server tutorials provided by Oracle).

I'm just wondering if there's a way to uniquely identify a connected client on the server side?

Answer 1

Yes, by the value of the Socket reference itself.

When a client connects to the server, store the Socket instance.
Then you can use it later to identify the connected client.
