Need some help with my first assignment

Hey, i'm a complete java newbie, i took a C++ class a year ago, and i did pretty well, so i know my way around loops. i already made a for loop that will run 100 times, the only problem now is i don't know the code that would allow the user to input something for the app to print.(i think in C++ it was called cin)

thanks in advance

Try using the String parameter from your main() and see if that works.
Or maybe use BufferedReader?

From the command prompt if you are in your development directory just type:
java nameofapp argument

The string you have provided as the argument is passed into main and if your code runs as anticipated, all should be well

You can get command-line parameters using the "args" array (sort of like in C++). To get user input while the program is running you can use the Console class (call System.console()).

There are links on the page with the assignment with tutorials. The one you're going to need is: http://www.javaranch.com/drive/command.html

Most assignments have some hints included in them or as links. Keep your eye out!
