Chapter 12 Exercise 26, Introduction to Java Programming, Tenth Edition Y. Daniel LiangY.

12.26 (Create a directory)
Write a program that prompts the user to enter a directory name
and creates a directory using the File’s mkdirs method. The program
displays the message “Directory created successfully” if a directory
is created or “Directory already exists” if the directory already exists.

import java.util.Scanner;
public class Exercise_26 {

    public static void main(String[] args) {

        Scanner input = new Scanner(;
        System.out.print("Enter a directory to create: ");
        File dir = new File(;

        if (!dir.exists() && dir.mkdir()) {
        } else {
            System.out.println("This directory already exits.");
