Create a directory if it does not exist and then create the files in that directory as well

To create a directory in Java if it does not exist, you can use the java.nio.file.Files class and its createDirectory method. Here is an example of how you can do this:

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

public class Main {
  public static void main(String[] args) throws Exception {
    String dirName = "mydir";
    Path dirPath = Paths.get(dirName);
    if (!Files.exists(dirPath)) {
      Files.createDirectory(dirPath);
    }
  }
}

This code creates a Path object representing the directory and then checks if it exists using the exists method. If the directory does not exist, it is created using the createDirectory method.

To create a file in the directory, you can use the java.nio.file.Files class and its createFile method. Here is an example of how you can do this:

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

public class Main {
  public static void main(String[] args) throws Exception {
    String dirName = "mydir";
    Path dirPath = Paths.get(dirName);
    if (!Files.exists(dirPath)) {
      Files.createDirectory(dirPath);
    }

    String fileName = "myfile.txt";
    Path filePath = dirPath.resolve(fileName);
    if (!Files.exists(filePath)) {
      Files.createFile(filePath);
    }
  }
}

This code creates a Path object representing the file and then checks if it exists using the exists method. If the file does not exist, it is created using the createFile method.

I hope this helps! Let me know if you have any other questions.
