Java如何删除文件夹呢?

实现思路:
    直接使用file对象的delete方法
	即可对文件夹进行删除操作

public static void deleteFileOrFolder(final Path path) throws IOException {
  Files.walkFileTree(path, new SimpleFileVisitor<Path>(){
    @Override public FileVisitResult visitFile(final Path file, final BasicFileAttributes attrs)
      throws IOException {
      Files.delete(file);
      return CONTINUE;
    }

    @Override public FileVisitResult visitFileFailed(final Path file, final IOException e) {
      return handleException(e);
    }

    private FileVisitResult handleException(final IOException e) {
      e.printStackTrace();  
      return TERMINATE;
    }

    @Override public FileVisitResult postVisitDirectory(final Path dir, final IOException e)
      throws IOException {
      if(e!=null)return handleException(e);
      Files.delete(dir);
      return CONTINUE;
    }
  });
};
