Create directory/directories in Eclipse with java.io.File

I tried to make it as easy as possible.

Example:

File  f = new File("non_existing_dir/someDir");
System.out.println(f.mkdir());
System.out.println(f.mkdirs());

mkdir() and mkdirs() return both false °_°. Both work (create directory) if i use double backslash \\ (like "\\non_existing_dir\\someDir" BUT:

if I do .toURI() after that I receive: file:/Users/MyName/Desktop/%5Cnon_existing_dir%5CsomeDir/

if I do .getPath() i receive: \non_existing_dir\someDir

if I do .getCanonicalPath() I receive: /Users/MyName/Desktop/\non_existing_dir\someDir



So i want to have instead this results:

with .toURI() receiving: file:/Users/MyName/Desktop/non_existing_dir/someDir/

with .getPath() receiving: /non_existing_dir/someDir

and with .getCanonicalPath() receiving: /Users/MyName/Desktop/non_existing_dir/someDir


Thanks in advance to everyone.

If non_existing_dir does not exists, you can check getParentFile() and create it with mkdir().

Also avoid problems between OS with File.separator.

String filename = "non_existing_dir"  + File.separator + "someDir";

File  f = new File(filename);
if (!f.exists()) {
    if (!f.getParentFile().exists()) {
         // make the dir
         f.getParentFile().mkdir();
    }
    f.mkdir();
}
