用java实现删除目录

	public static void main(String[] args) {
		try {
			String strFolder = "D:\\aa";
			deleteFile(new File(strFolder));

			System.out.println("Delete Successful!");
		} catch (Exception e) {
			System.out.println(e.getMessage());
			System.out.println("Delete Fail!");
		}
	}

	public static void deleteFile(File file) {

		if (file == null || !file.exists()) {
			return;
		}

		File[] files = file.listFiles();
		for (File f : files) {
			if (f.isDirectory()) {
				deleteFile(f);
			} else {
				f.delete();
			}
		}
		file.delete();
