Java - create multiple subfolders

In this article, we would like to show you how to create multiple subdirectories (subfolders) in Java.

Directory/
  |
  +-- subDirectory1/
  |
  +-- subDirectory2/
  |
  +-- subDirectoryN/

Practical example

In this example, we create 5 new folders under the given path. To do so we use mkdir() method inside the for loop.

import java.io.File;

public class Example {

    public static void main(String[] args) {
        String myDirectoryPath = "C:\\projects\\example\\newFolder";

        for (int i = 0; i < 5; i++) {
            File myDirectory = new File(myDirectoryPath + "_" + i);

            if (!myDirectory.exists()) {
                if (myDirectory.mkdir()) {
                    System.out.println(myDirectory.getName() + " created successfully.");
                } else {
                    System.out.println("Couldn't create " + myDirectory.getName());
                }
            } else {
                System.out.println(myDirectory.getName() + " already exists.");
            }
        }
    }
}

result:

newFolder_0 created successfully.
newFolder_1 created successfully.
newFolder_2 created successfully.
newFolder_3 created successfully.
newFolder_4 created successfully.
