java - 关闭后如何再次打开服务器套接字？

Question

I'm using ServerSocket object in my project. Basically, I have a button which closes socket and open it again. How can I do this ? I can close socket. However, cannot open it.

Answer 1

You can not do that, take a look to the doc

particullarly this line:

Once a socket has been closed, it is not available for further networking use (ie can't be reconnected or rebound). A new socket needs to be created.

close

public void close() throws IOException Closes this socket. Any thread currently blocked in an I/O operation upon this socket will throw a SocketException.

Once a socket has been closed, it is not available for further networking use (ie can't be reconnected or rebound). A new socket needs to be created.

Closing this socket will also close the socket's InputStream and OutputStream.

If this socket has an associated channel then the channel is closed as well.

Throws: IOException - if an I/O error occurs when closing this socket. See Also: isClosed()
