about the returned Socket object from SocketServer

I have a very simple question, however I am confused by a tutorial.

Say, I create a server & use port 1234:

ServerSocket server = new ServerSocket(1234);

Then, I ask server to wait for requests by:

while(true) {
  // is the returned socket represents the server side socket or client side socket???
  Socket socket = server.accept();
}

My question is whether the socket returned by server.accept() a server side socket or client side socket? It is not very well explained in Java doc.

The reason why I ask this question is because when I run socket.getPort(), it doesn't return server port 1234, instead, it returns a port not defined by me, so, I am thinking it might be the client's socket. But I am not sure.

Solution

  • Listens for a connection to be made to this socket and accepts it. The method blocks until a connection is made.

    which means, that it is server.

    socket.getPort() according to javadoc,

    Returns the remote port number to which this socket is connected.
