How to create a directory in project folder using Java?
The class named File of the java.io package represents a file or directory (path names) in the system. This class provides various methods to perform various operations on files/directories.
The mkdir() method of this class creates a directory with the path represented by the current object.
Therefore, to create a directory −
Instantiate the File class by passing the path of the directory you need to create, as a parameter (String).
Invoke the mkdir() method using the above-created file object.
Example
The following Java example reads the path and name of the directory to be created, from the user, and creates it.
import java.io.File;
import java.util.Scanner;
public class CreateDirectory {
public static void main(String args[]) {
System.out.println("Enter the path to create a directory: ");
Scanner sc = new Scanner(System.in);
String path = sc.next();
System.out.println("Enter the name of the desired a directory: ");
path = path+sc.next();
//Creating a File object
File file = new File(path);
//Creating the directory
boolean bool = file.mkdir();
if(bool){
System.out.println("Directory created successfully");
} else {
System.out.println("Sorry couldn’t create specified directory");
}
}
}Output
Enter the path to create a directory: D:\ Enter the name of the desired a directory: sample_directory Directory created successfully
If you verify, you can observe see the created directory as −
But, if you specify a path in a drive that doesn’t exist, this method will not create the required directory.
For example, if the D drive of my (windows) system is empty and if I specify the path of the directory to be created as −
D:\test\myDirectories\sample_directory
Where the test and myDirectories folders don’t exist, the mkdir() method will not create it.
