package pack1;

import java.io.File;
import java.util.Scanner;

public class CreateDirectory {
    public static void main(String[] args) {
        try(Scanner input = new Scanner(System.in);) {
            System.out.print("Enter a directory name: ");
            File directory = new File(input.next());

            if (directory.exists())
                System.out.println("Directory already exists");
            else {
                directory.mkdir();
                System.out.println(directory.exists()  ? "Directory created successfully" : "Error directory name");
            }
        }
