File isFile   is false if the file   directory does not exist  so you can t use it to test whether you re trying to create a directory  But that s not the first issue here   The issue is that the intermediate directories don t exist  You want to call f mkdirs   first

If the directory     foo bar  doesn t exist  you can t create a file there  so make sure you create the directory first   Try something like this   File f   new File  somedirname1 somedirname2 somefilename    if   f getParentFile   exists        f getParentFile   mkdirs    if   f exists        f createNewFile

You may want to use Apache Commons IO s FileUtils openOutputStream File  method  It has good Exception messages when something went wrong and also creates necessary parent dirs  If everything was right then you directly get your OutputStream  - very neat   If you just want to touch the file then use FileUtils touch File  instead
