How to create a directory in Java?

How do I create Directory/folder?

Once I have tested System.getProperty("user.home");

I have to create a directory (directory name "new folder" ) if and only if new folder does not exist.

Solution 1:

new File("/path/directory").mkdirs();

Here "directory" is the name of the directory you want to create/exist.

Solution 2:

After ~7 year, I will update it to better approach which is suggested by Bozho.

File theDir = new File("/path/directory");
if (!theDir.exists()){
    theDir.mkdirs();
}

Solution 3:

With Java 7, you can use Files.createDirectories().

For instance:

Files.createDirectories(Paths.get("/path/to/directory"));
