Starting from Java 7, you can use the java.nio.file.Files & java.nio.file.Paths classes.

Path path = Paths.get("C:\\Images\\Background\\..\\Foreground\\Necklace\\..\\Earrings\\..\\Etc");

try {
    Files.createDirectories(path);
} catch (IOException e) {
    System.err.println("Cannot create directories - " + e);
}

This is a tricky solution (because I used only one path to go to the whole structure).

If you don't like tricky solutions, you can use 4 simple paths instead:

Path p1 = Paths.get("C:\\Images\\Background");
Path p2 = Paths.get("C:\\Images\\Foreground\\Necklace");
Path p3 = Paths.get("C:\\Images\\Foreground\\Earrings");
Path p4 = Paths.get("C:\\Images\\Foreground\\Etc");

and then call the createDirectories method for all of them:

Files.createDirectories(p1);
Files.createDirectories(p2);
Files.createDirectories(p3);
Files.createDirectories(p4);
