java 删除非空文件夹

java 中如何删除非空的目录呢？

使用递归，代码如下：

/***
	 * delete a directory/folder
	 * 
	 * @param someFile
	 */
	public static boolean deleteDir(File someFile) {
		if (!someFile.exists()) {
			System.out.println("[deleteDir]File " + someFile.getAbsolutePath()
					+ " does not exist.");
			return false;
		}
		if (someFile.isDirectory()) {// is a folder
			File[] files = someFile.listFiles();
			for (File subFile : files) {
				boolean isSuccess = deleteDir(subFile);
				if (!isSuccess) {
					return isSuccess;
				}
			}
		} else {// is a regular file
			boolean isSuccess = someFile.delete();
			if (!isSuccess) {
				return isSuccess;
			}
		}
		if (someFile.isDirectory()) {
			return someFile.delete();
		} else {
			return true;
		}
	}

 说明：若删除成功，则返回true，否则返回false
