Answer 1

Guava also has Files.createParentDirs(File).

Answer 2

Since the question also mentioned the library Apache Common IO, I report in the following a solution that uses this nice library:

File file = new File("...  the directory path ..."); 
FileUtils.forceMkdir(file);

This solution uses the class FileUtils, from package org.apache.commons.io and the method forceMkdir, that "Makes a directory, including any necessary but nonexistent parent directories".

Answer 3

new File("some/path/to/somewhere/then-my-file").getParentFile().mkdirs()
