Java：使用命令行参数将文件名传递给程序

Question

Okay, so I'm not entirely sure what I'm doing here.

I have an assignment that requires that I read files called student.txt and classes.txt as well as a couple others and from those create a grade report.

However in my assignment it is required that "file names “student.txt” and “classes.txt” must be passed to the program through command line arguments." I'm not entirely sure what this means.

Throughout my programming class we've been running NetBeans IDE and I honestly don't ever remember him mentioning command line arguments (although I did miss a day last week).

I've looked up tons of tutorials online but anything I've seen has been about using user entered arguments and not files so I have absolutely no idea what to do.

I googled "netbeans command line arguments" and found a very helpful article: http://netbeanside61.blogspot.com/2009/02/using-command-line-arguments-in.html

It not only describes how to use NetBeans to pass command line arguments to a Java program, it also demonstrates how to access those arguments from your Java code.
