import java.io.*;
import java.util.*;
public class DirUtils {

  public static List recurseDir(String dir) {
      String result, _result[];

      result = recurseInDirFrom(dir);
      _result = result.split("\\|");
      return Arrays.asList(_result);
  }

  private static String recurseInDirFrom(String dirItem) {
    File file;
    String  result,list[];

    result = dirItem;

    file = new File(dirItem);
    if (file.isDirectory()) {
      list = file.list();
      File[] fileslist = file.listFiles(new MyDocFileFilter());
    if (fileslist != null) {
      for (File file1: fileslist) {
        System.out.println(file1.getAbsolutePath());
      }
    } 
    else {
      System.out.println("No Subdirectory Found.");
    }
      for (int i = 0; i < list.length; i++)
        result = result + "\n" + recurseInDirFrom(dirItem + File.separatorChar + list[i]);
      }
    return result;
  }

 static class MyDocFileFilter implements FileFilter
{
  private final String[] myDocumentExtensions 
               = new String[] {".java", ".png", ".html", "class"};

  public boolean accept(File file) {

    if (!file.isFile())
        return false;

    for (String extension : myDocumentExtensions) {
      if (file.getName().toLowerCase().endsWith(extension))
        return true;
    }
    return false;
  }
}

  public static void main(String arg[]) {
    DirUtils.recurseDir("your path ");
