Java: Listing all files and folders, including sub directories

Hi Everyone

I am trying to write a java program that simple outputs to a text file using >> file.txt pipes.

The program needs to start are one directory and then travel througha ll sub directories listing all files and folders within. I have includes my code so far, but all it does is list 2 directories deep, i need some kind of recursion but im a bit new at this, please help....


import java.io.File;

public class DirectoryReader {

public static void main(String[] args) {

String dir = "/";
File folder = new File(dir);
File[] listOfFiles = folder.listFiles();

for (int i = 0; i < listOfFiles.length; i++) {
if (listOfFiles[i].isFile()) {
System.out.println("[FILE]" + listOfFiles[i].getName());
} else if (listOfFiles[i].isDirectory()) {

String directoryToSearch = listOfFiles[i].getName();
System.out.println("[DIR]" + directoryToSearch);

File subFolder = new File(dir + directoryToSearch);
File[] listOfSubFiles = subFolder.listFiles();
for (int j = 0; j < listOfSubFiles.length; j++){
System.out.println("\t[DIR]" + listOfSubFiles[j].getName());
}

}
}
}

}

old post, but just fooling around (i'm no java programmer) :

import java.io.File;

public class DirectoryReader {

  static int spc_count=-1;

  static void Process(File aFile) {
    spc_count++;
    String spcs = "";
    for (int i = 0; i < spc_count; i++)
      spcs += " ";
    if(aFile.isFile())
      System.out.println(spcs + "[FILE] " + aFile.getName());
    else if (aFile.isDirectory()) {
      System.out.println(spcs + "[DIR] " + aFile.getName());
      File[] listOfFiles = aFile.listFiles();
      if(listOfFiles!=null) {
        for (int i = 0; i < listOfFiles.length; i++)
          Process(listOfFiles[i]);
      } else {
        System.out.println(spcs + " [ACCESS DENIED]");
      }
    }
    spc_count--;
  }

  public static void main(String[] args) {
    String nam = "/";
    File aFile = new File(nam);
    Process(aFile);
  }

}
