Java - create file and dir

Question

Assume final String fname = "/dir1/dir2/fname.ext". I do not wish to parse the string recursively in order to create the directories if they do not exist, and only then write to a file. I wish to use the given string, fname, for creating the directories and file if each of which does not exist.

Perfect, now we know what you like to do... what have you tried so far? — home

This is the code you are looking for:

File myFile = new File("/dir1/dir2/fname.ext");
myFile.getParentFile().mkdirs();
// do your writing being sure the parent directories exist.

Please correct to myFile.getParentFile().mkdirs() so I could mark your post as an answer; and... thank you.

@MrRoth I think it was long corrected before you post your comment.

You can use mkdirs to create the path.

File f = new File("/dir1/dir2/fname.ext");
f.getParentFile().mkdirs();

And then work on the file itself.
