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 folderFile[] files = someFile.listFiles();for (File subFile : files) {boolean isSuccess = deleteDir(subFile);if (!isSuccess) {return isSuccess;}}} else {// is a regular fileboolean 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
