Re: setting path

Question

Grettings, I have a simple question.
I have several java programs that I have written and that work successfully. My problem is that I am running these codes on numerous files located in several places. I would like to set the execution path rather than copying the files (code) to oodles of locations and then executing them from there. Perhaps I am not using the correct terminology, for most of my searches have led me towards j2sdk1.4.1 and classpaths. As always, any constructive critisms are warmly appreciated.

Answer 1

Fair question. I have several java files that I am using. I will list the simpliest one below.
// simple program for creating empty text files
import java.io.*;
import javax.swing.*;
public class addText
     public static void main(String args[]) throws Exception
          String fNumber;
          int numOfFiles;
          fNumber = JOptionPane.showInputDialog("Enter number of files");
          numOfFiles = Integer.parseInt(fNumber);
          String file;
          int fileName;
          file = JOptionPane.showInputDialog("Enter name/number of first file");
          fileName = Integer.parseInt(file);
          for (int iterator = fileName; iterator <= numOfFiles + fileName - 1; iterator++)
               Integer.toString(iterator); //converts integer to a string
               File f  = new File(iterator + ".txt"); //using the string "integer" to name a file
               f.createNewFile();      // creates the file
}So, I have several directories containing subdirectories. I need to execute the above program in files located in all the the dir/subdirectories. Up to this point I have been coping the above code to each folder in the dir/subdirectories and then compiling/executing the code. It is time consuming to copy the code to each location, and heaven forbid I need alter the code at some point. I would need to change (or copy) the code in each location. I hope that is a bit clearer.
