在一个ServerSocket和几个套接字之间进行通信

Question

我试图让我的ServerSocket与多个Socket通信，但我不知道如何，到目前为止我意识到调用serverSocket.accept（）将返回一个套接字在服务器和第一个套接字之间进行通信，但是当第二个和之后正在尝试连接到ServerSocket，它让它们连接，但没有得到一个新的套接字与它们通信，所以，我如何与第二个Socket进行通信？

Simply put, you need to spawn a new thread if you want to communicate with both sockets at the same time.

ServerSocket ss = new ServerSocket(... params ...);
while(isRunning) {
    Socket socket = ss.accept();
    Runnable r = new SocketHandler(socket); // write the socket handler class
    Thread t = new Thread(r);
    t.start();
} 

Now obviously there are many, many improvements you can make to this. The most obvious would be holding on to the references of r and/or t so you have better/tighter control over them, and the ability to stop them at will. But those features are well beyond the scope of this question.
