How can I delete a dir which has sub-dir's ?

Question

Dear list,
Can some one send me a link or send me a code example of how to delete all the sub- directories in a specified directory. My dir has sub-directories which contain files!
If I use the java.io package I must loop all the sub- directories, and java.io.File.delete() wont delete a dir when it contains files, so I will have to go into each sub-dir and delete the files before deleting the sub-dir. This is going to be a lot of code, and YES ! I am a little lazy!
Is there a java package, with a method, where I can just delete a dir, which just deletes it and ALL its contents ?
regards
BB

    // Delete an empty directory
    boolean success = (new File("directoryName")).delete();
    if (!success) {
        // Deletion failed
    }If the directory is not empty, it is necessary to first recursively delete all files and subdirectories in the directory. Here is a method that will delete a non-empty directory.     // Deletes all files and subdirectories under dir.
    // Returns true if all deletions were successful.
    // If a deletion fails, the method stops attempting to delete and returns false.
    public static boolean deleteDir(File dir) {
        if (dir.isDirectory()) {
            String[] children = dir.list();
            for (int i=0; i<children.length; i++) {
                boolean success = deleteDir(new File(dir, children));
if (!success) {
return false;
// The directory is now empty so delete it
return dir.delete();
