In this article, we would like to show you how to list all directory names from the directory in Java.

Quick solution:

File[] directories = new File(path).listFiles(File::isDirectory); // get array of directories

 

Practical example

In this example, we use listFiles() method and check if the file is a directory to list all directories from the directory specified by path.

Java - list all directories (example data)
Java - list all directories (example data)

Example.java: 

import java.io.File;
import java.util.Objects;

public class Example {

    public static void main(String[] args) {
        String path = "C:\\projects\\example";
        File[] directories = new File(path).listFiles(File::isDirectory); // array of directories

        File[] list = Objects.requireNonNull(directories); // creates list if directories != null

        for (File item : list) {
            System.out.println(item.getName());
        }
    }
}

Result:

Folder1
Folder2

Note:

To get full directory paths instead of firectory names remove getName() from item.getName() inside for loop.

Result:

C:\projects\example\Folder1
C:\projects\example\Folder2
