是否可以读取目录中所有文件夹的名称(而不是子文件夹)，并将列表保存在ArrayList等中?

Is it possible to read all the names of folders (not sub-folders) inside a directory and save the list in an ArrayList, etc ?

例如-如果目录中包含以下文件夹-CLIENT1，CLIENT2，CLIENT3等. 我希望ArrayList像这样-[CLIENT1，CLIENT2，CLIENT3等].

e.g- if a directory has the following folders inside it- CLIENT1, CLIENT2, CLIENT3, etc. I want the ArrayList to be something like this- [CLIENT1, CLIENT2, CLIENT3, etc].

这些文件夹位于Unix服务器中，因此可以使用Java代码或Shell脚本(bash/tcsh/etc)或它们的组合来完成.

The folders are in an unix server, so either java code or a shell script(bash/tcsh/etc) or their combination would do.

推荐答案

尝试一下:

File dir = new File("directoryName"); File temp; String[] children = dir.list(); if (children !=null) { for (int i=0; i<children.length; i++) { temp = new File(children[i]); if(temp.isDirectory()) //add children[i] to arrayList } }
