Question

I’m a writing a program that will determine the number of lines, characters, and average word length for a text file. For the program, the specifications say that the file or files will be entered as a command line argument and that we should make a TestStatistic object for each file entered. I don’t understand how to write the code for making the TestStatistic objects if the user enters more than one file.

Answer 1

The most basic way to process command line arguments is:

public class TestProgram
{
    public static void main(final String[] args)
    {
        for (String s : args)
        {
            // do something with each arg
        }
        System.exit(0);
    }
}

The preferable way is to use something that manages the command line arguments for you. I suggest JSAP: The Java Simple Argument Parser.
