Java Programming

Hi

Could someone point me to a simple guide for creating Java apps with CVS files.

I have an excel file that I have converted to .csv just by changing it in the file > save as window to cvs.

I need to read values from this file and cross-check a particulat column of data (Date/Time of order) against the current day's date/time in order to highlight 24 hour notice ordering for customers.

First off, what is it I need to do/understand when using a file such as this where I will be reading data from it?

I have had a look at stuff on the net but most of it seems to become quite complicated quite quickly and I don't really understand what they are trying to achieve.

What would be good would be to create a simple app first where I just read the data and display it in cmd line for example, then build on that, just to prove to myself that I understand each step.

Thanks for any pointers.
