How can I create an empty folder in Java?
File f = new File("C:\\TEST");
try{
if(f.mkdir()) {
System.out.println("Directory Created");
} else {
System.out.println("Directory is not created");
}
} catch(Exception e){
e.printStackTrace();
}
Call File.mkdir
, like this:
new File(path).mkdir();
With Java 7 and newer you can use the static Files.createDirectory() method of the java.nio.file.Files
class along with Paths.get
.
Files.createDirectory(Paths.get("/path/to/folder"));
The method Files.createDirectories() also creates parent directories if these do not exist.
Use mkdir()
:
new File('/path/to/folder').mkdir();
Use the mkdir method on the File class:
http://java.sun.com/j2se/1.4.2/docs/api/java/io/File.html#mkdir%28%29
Using Java 8:
Files.createDirectories(Paths.get("/path/to/folder"));
Same:
new File("/path/to/folder").mkdirs();
Or
Files.createDirectory(Paths.get("/path/to/folder"));
Same:
new File("/path/to/folder").mkdir();
Better to use mkdirs
as:
new File("dirPath/").mkdirs();
mkdirs
: also create parent directories if these do not exist.
ps: don't forget the ending /
that shows explicitly you want to make a directory.
The following code would be helpful for the creation of single or multiple directories:
import java.io.File;
public class CreateSingleOrMultipleDirectory{
public static void main(String[] args) {
//To create single directory
File file = new File("D:\\Test");
if (!file.exists()) {
if (file.mkdir()) {
System.out.println("Folder/Directory is created successfully");
} else {
System.out.println("Directory/Folder creation failed!!!");
}
}
//To create multiple directories
File files = new File("D:\\Test1\\Test2\\Test3");
if (!files.exists()) {
if (files.mkdirs()) {
System.out.println("Multiple directories are created successfully");
} else {
System.out.println("Failed to create multiple directories!!!");
}
}
}
}
