Create whole path automatically when writing to a new file

Question

Hi,

I want to write a new file with the Java FileWriter. I use it like this:

FileWriter newJsp = new FileWriter("C:\\user\Desktop\dir1\dir2\filename.txt");

Now the dir1 and dir2 currently don't exist. I want Java to create them automatically if they aren't already there. Actually Java should set up the whole file path if not already existing.

How can I achieve this?

Answer 1

Use File.mkdirs().

Answer 2

Use File.mkdirs():

File dir = new File("C:\\user\\Desktop\\dir1\\dir2");
dir.mkdirs();
File file = new File(dir, "filename.txt");
FileWriter newJsp = new FileWriter(file);

Answer 3

Something like:

File file = new File("C:\\user\\Desktop\\dir1\\dir2\\filename.txt");
file.getParentFile().mkdirs();
FileWriter writer = new FileWriter(file);
