Create a New folder using Java Program on Windows and Linux machines

Question

How can I create a Folder using Java code on both Windows and Linux machines?

Answer 1

new File("/path/to/folder").mkdir();

If you want to created nested folders (i.e. more than one folder on the path may be missing), then use mkdirs(). See java.io.File.

Note that forward slashes would normally not work on windows, but Java normalizes the path and translates forward to backward slashes.
