How to create a folder in Java?

Question

How can I create an empty folder in Java?

Answer 1

Use the mkdir method on the File class:

Answer 2

Better to use mkdirs as:

new File("dirPath/").mkdirs();

mkdirs: also create parent directories if these do not exist.

ps: don't forget the ending / that shows explicitly you want to make a directory.
