Create New Folder with Dynamic Name

Method to create a single Folder/ Directory with date-time as dynamic name:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
public static void mkSingleDir(String dirPath, String dirName){

    File file = new File(dirPath+dirName);
    if (!file.exists()) {
        if (file.mkdir()) {
            System.out.println("Directory is created!");
        } else {
            System.out.println("Failed to create directory!");
        }
    }else{
     System.out.println("Directory exists: "+file); 
    }  
}


Method to create multiple Folders/ Directories simultaneously:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
public static void mkMultipleDir(String dirPath){
 // Eg.: "C:\\Directory2\\Sub2\\Sub-Sub2"
 File files = new File(dirPath); 
    if (!files.exists()) {
        if (files.mkdirs()) {
            System.out.println("Multiple directories are created!");
        } else {
            System.out.println("Failed to create multiple directories!");
        }
    }else{
     System.out.println("Directory exists: "+file); 
    }
}


And this is how we call the above methods to use them:
(We will code the dynamic part of the new Folder/ Directory name here)

1
2
3
4
5
6
7
public static void main(String[] args) {
 
 mkSingleDir("C:/Users/jigyasa/Desktop/","sampleDir2");
 mkMultipleDir("C:/Users/jigyasa/Desktop/sampleDir3/sampleSubDir03");     
 String file = new SimpleDateFormat("yyyy-MM-dd_hh-mm-ss'.xls'").format(new Date());
 System.out.println(file);
}


So basically, these methods will check weather the directory exists and create it if it does not. If the directory exists then the user will be prompted a message that the directory already exists and the path of the directory.
