How to use Files.createDirectories() method

For example, we want to create all parent and sub directories for the path D:\SimpleSolution\Data\Java\JavaNIO , we can use the Files.createDirectories() method as the following Java application.

FilesCreateDirectoriesExample1.java 

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class FilesCreateDirectoriesExample1 {
    public static void main(String... args) throws IOException {
        Path directoryToCreate = Paths.get("D:\\SimpleSolution\\Data\\Java\\JavaNIO");

        Path createdDirectories = Files.createDirectories(directoryToCreate);

        System.out.println("Successful create directories: " + createdDirectories.toString());
    }
}
The output as below. 
Successful create directories: D:\SimpleSolution\Data\Java\JavaNIO

More Files.createDirectories() Java Examples

In the following Java program, we use Files.createDirectories() method to create directories inside temporary directory.

FilesCreateDirectoriesExample2.java 

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;

public class FilesCreateDirectoriesExample2 {
    public static void main(String... args) throws IOException {
        Path tempDirectory = Files.createTempDirectory("TestCreateDirectory");
        Path directoryToCreate = tempDirectory.resolve("Simple").resolve("Solution").resolve("Java");

        Path createdDirectories = Files.createDirectories(directoryToCreate);

        System.out.println("Successful create directories: " + createdDirectories.toString());
    }
}
The output as below. 
Successful create directories: C:\Users\SS\AppData\Local\Temp\TestCreateDirectory8802687788553334892\Simple\Solution\Java
