Attach Javadoc about Files.createTempDirectory().
https://docs.oracle.com/javase/8/docs/api/java/nio/file/Files.html#createTempDirectory-java.nio.file.Path-java.lang.String-java.nio.file.attribute.FileAttribute...-
Considering that this method can loop generate random names until file or
directory can be created, And invoked to check write access when creating the
directory. So it didn't need to delete and mkdir again IMO. FYI.
