challenging) Create a client/server pair of programs that use datagrams to
transmit a file from one machine to the other. (See the description at the end
of the datagram section of this chapter.)
challenging) Take the
program and modify it so that when you click on the resulting name it
automatically takes that name and copies it to the clipboard (so you can simply
paste it into your email). You’ll need to look back at the IO stream
chapter to remember how to use the Java 1.1 clipboard.
