I got a homework. This is too difficult to me. Because, I have just learned about the introduction of Java Networking. I still didn't get a enough material about Java Networking programming.

This is the task that I got: https://dl.dropboxusercontent.com/u/61841244/CS1103%20-%20T1%202013-2014_%20Lab%2011%20Unit%207.pdf

This is my question :
- what is the final result of this task ?
- what must I do ?

Thank you.

the answer to your first question is basically the very first sentence in that pdf document.
what you have to do is explained in the rest of the document. for certain parts, you are already given ready-made code to copy-paste.
