Deleting a directory and its content

Question

Hi, I'm trying to delete a series of directories like this batch file does
@echo Removing "%CD%\a"
@rmdir /s /q "%CD%\a"
@echo Removing "%CD%\b"
@rmdir /s /q "%CD%\b"
@echo Removing "%CD%\c"
@rmdir /s /q "%CD%\c"looking at the api i found that it doesn't seem to have the option to delete a dir and its content, should i use a function like the one in thread:
http://forum.java.sun.com/thread.jsp?forum=31&thread=188034
or would it be better to call the batch script with Runtime.exec()? The system is windows only so i don''t need to have compatibility with *nix shells ect.
What do you think?

Try this
// CLASS:    FileUtil
// FUNCTION: An extension of File which allows various file manipulations
import java.io.*;
import java.net.*;
import java.util.*;
public class FileUtil
    extends File {
   public FileUtil(File parent, String child) throws NullPointerException {
      super(parent, child);
   public FileUtil(String pathname) throws NullPointerException {
      super(pathname);
   public FileUtil(String parent, String child) throws NullPointerException {
      super(parent, child);
   public FileUtil(URI uri) throws IllegalArgumentException, NullPointerException {
      super(uri);
   public void deleteTree() throws Exception {
      ArrayList contents = new ArrayList();
      listContents(contents);
      File f;
      for (int i = contents.size() - 1; i >= 0; i--) {
      f = new File( (String) contents.get(i));
      f.delete();
   private void listContents(ArrayList files) throws Exception {
      listContents(files, this);
   private void listContents(ArrayList files, File dir) throws Exception {
      System.out.println(dir.getAbsolutePath());
      File[] newFiles = dir.listFiles();
      File newFile;
      if (newFiles != null) {
      for (int i = 0; i < newFiles.length; i++) {
         newFile = new File(newFiles.getAbsolutePath());
     files.add(newFiles[i].getAbsolutePath());
     if (newFile.isDirectory()) {
     listContents(files, newFile);
