I know how to create directory but I need to create sub directory I tried with following code what should be next steps ?

File file = new File("Images");
file.mkdir();

推荐答案

你可以使用 File.mkdir（）或 File.mkdirs（）创建目录。在这两者之间，后一种方法更宽容，并将根据需要创建所有中间目录。此外，由于我发现您在问题中使用\\，我建议使用 File.separator ，用于可移植路径分隔符字符串。

You can use File.mkdir() or File.mkdirs() to create a directory. Between the two, the latter method is more tolerant and will create all intermediate directories as needed. Also, since I see that you use "\\" in your question, I would suggest using File.separator for a portable path separator string.
