Examples of java.net.ServerSocket

java.net.ServerSocket
This class implements server sockets. A server socket waits for requests to come in over the network. It performs some operation based on that request, and then possibly returns a result to the requester.
The actual work of the server socket is performed by an instance of the SocketImpl class. An application can change the socket factory that creates the socket implementation to configure itself to create sockets appropriate to the local firewall. @author unascribed @version 1.91, 03/08/07 @see java.net.SocketImpl @see java.net.ServerSocket#setSocketFactory(java.net.SocketImplFactory) @see java.nio.channels.ServerSocketChannel @since JDK1.0
