Datagrams in J2ME (UDP Programming sample)

Datagrams in J2ME (UDP Programming sample): "It is quite possible for someone to have worked with Java for some time without ever needing to understand or use datagrams. For mobile devices, however, datagrams offer some advantages in that they are rather lightweight when compared to TCP-based connections such as sockets. User Datagram Protocol, UDP, is one of the more common datagram protocols. However, because most datagram protocols follow the same basic principals as to their usage, the GCF is able to support datagrams generically."
