The last three methods provide the same service for the local address and port. If the socket has not been bound to a local address, getLocalAddress() returns the wildcard (“any local address”) address. getLocalPort() always returns a local port number; if the socket was not been bound before the call, the call causes the socket to be bound to any available local port. The getLocalSocketAddress() returns null if the socket is not bound. DatagramSocket: Sending and receiving void send(DatagramPacket packet) void receive(DatagramPacket packet) 34 Chapter 2: Basic Sockets The send() method sends the DatagramPacket.
This agreement regarding the form and meaning of information exchanged over a communication channel is called a protocol; a protocol used in implementing a particular application is an application protocol. In our echo example from the earlier chapters, the application protocol is trivial: neither the client’s nor the server’s behavior is aﬀected by the contents of the messages they exchange. Because in most real applications the behavior of clients and servers depends upon the information they exchange, application protocols are usually somewhat more complicated.
The destination address and port may be speciﬁed separately, or together in a SocketAddress. DatagramPacket: Addressing InetAddress getAddress() void setAddress(InetAddress address) int getPort() void setPort(int port) SocketAddress getSocketAddress() void setSocketAddress(SocketAddress sockAddr) In addition to constructors, these methods supply an alternative way to access and modify the address of a DatagramPacket. Note that in addition, the receive() method of DatagramSocket sets the address and port to the datagram sender’s address and port.
