Reading a file using Scanner

Hi, I'm trying to learn using Scanner to analyse a file. The running of the program does not work. I have included below code, directory structure and out. Could someone help please. I am using Netbeans.

*****************************************************************************************
************************************ The Code *******************

package packagetwo;

import java.io.*;
import java.io.File;
import java.util.Scanner;

/**

public class TSD2 {

public static void main(String[] args){

String[] fileList = null;

//use this for testing purposes
File f = new File("C:\\Installs\\Java\\Workspace\\NetBeans\\" +
"Projects\\MyProjects\\src\\packagetwo\\TestDirectory");

//is this main path a directory
if (f.isDirectory()){
System.out.println("");
System.out.println("");
System.out.println("it is a directory");

fileList = f.list();
for(int i=0;i<fileList.length;i++){
File firstFile = new File(fileList[i]);

System.out.println(firstFile.toString());

try{

if (!(firstFile.isDirectory())){
System.out.println("it is not a directory");
Scanner scannedFile = new Scanner(firstFile);
System.out.println("done");
}

if ((firstFile.isDirectory())){
String name = firstFile.toString();
System.out.println(name + "is a directory .... " + "\n");
}

}catch(FileNotFoundException fne){fne.printStackTrace();}
}
}
}
}

*****************************************************************************************
************************************ The Directory Structure of the test file *******************

C:\Installs\Java\Workspace\NetBeans\Projects\MyProjects\src\packagetwo\TestDirectory\SelfEmployedA.text

create a file named SelfEmployedA.txt in the folder from where you are running the program. If what I think is right, then it will then work.

Also please UseCodeTags to make your program readable...

Thank you for the reply. I have placed a 'SelfEmployedA.txt' file in the same directory from which I am running the application. It also does not seem to want to work. I really am baffled.

//this is the Application program
C:\Installs\Java\Workspace\NetBeans\Projects\MyProjects\src\packagetwo\TSD2.java

//this is the file in the same directory
C:\Installs\Java\Workspace\NetBeans\Projects\MyProjects\src\packagetwo\SelfEmployedA.txt

//these are picked up in the hard coded directory in the program (File f = new File("C:\\Installs\\..........\\TestDirectory"))
C:\Installs\Java\Workspace\NetBeans\Projects\MyProjects\src\packagetwo\TestDirectory\SelfEmployedA.txt
C:\Installs\Java\Workspace\NetBeans\Projects\MyProjects\src\packagetwo\TestDirectory\TestDirectoryOne

Nope, the program gets executed from "C:\Installs\Java\Workspace\NetBeans\Projects\MyProjects" which is where your 'SelfEmployedA.txt' file should be.

If you are facing that sort of problem, turn NetBeans off and use a simple class called from the command line.
Beware: when you call nextInt and enter "123return" the Scanner will interpret the "123" bit as the int and the return as a line which is blank. If you go back through this forum you will find at least two threads in the last week where people have problems with Scanners: try here and here (towards the bottom of the page) and maybe even here, and see whether there is anything helpful there.
