We will help you as soon you show us what you did so far. However, NOBODY will do your homework for you

Yeah we aren't allowed to help with homework unless effort has been shown. But to get you started:

java myprog

is actually asking java to execute the file myprog.class so of course you must have compiled it first.
By typing:

java myprog data1 data2 data3

you cause args to store the following information:

args[0] = "data1"
args[1] = "data2"
args[2] = "data3"

You can find out how many elements are stored in args by using the fact that it's an array:

len = args.length;

Note that length is variable, not a method as with the String class. Well that's a good start off I'm sure :) Oh check out http://java.sun.com/docs/books/tutorial/essential/environment/cmdLineArgs.html

All the best!
