java.nio.file.FileAlreadyExistsException | java.nio.file.NoSuchFileException

Trying to create multiple directories using the createDirectory() method will throw a NoSuchFileException. Instead use the createDirectories() method. 

Trying to create a directory that already exists will throw a FileAlreadyExistsException. i.e running the same code used to create a single directory more than once on the same path/filename.
See Code Snippet below.

import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.FileSystems;       
import java.nio.file.Files;
import java.io.IOException;
import static java.lang.System.err;

public class OcpPrepare {
    public static void main(String[] args) {
    
     //-----------First Part-----------//
    //trying to create multiple direcotries One, Two and Three
        Path newDir = FileSystems.getDefault().getPath("C:\\Users\\", "One\\Two\\Three");      
        try{
        Files.createDirectory(newDir);
        }
        catch(IOException e){
            err.println(e); //NoSuchFileException Thrown ;; 
        }
//-----------Second Part-----------//
//trying to create a directory that already exist
        Path newDir = FileSystems.getDefault().getPath("C:\\Users\\One");      
        try{
        Files.createDirectory(newDir);
        }
        catch(IOException e){
            err.println(e); //FileAlreadyExistsException Thrown ;; 
        }
    }
