public class Example {4

public static void listDirectoriesInDirectory(File directoryPath) {6
File[] filesList = directoryPath.listFiles();7
for (File file : filesList) {8
if (file.isDirectory()) {9
System.out.println(file);10
listDirectoriesInDirectory(file);11
}12
}13
}14

public static void main(String[] args) {16
File directoryPath = new File("C:\\project");17
listDirectoriesInDirectory(directoryPath);18
}19
}Output:

C:\project\directory12
C:\project\directory1\directory33
C:\project\directory2xxxxxxxxxx1

public static void main(String[] args) throws IOException {8
Files.find(Paths.get("C:\\project"),9
Integer.MAX_VALUE, // the maximum number of directory levels to search10
(filePath, FileAttributes) -> FileAttributes.isDirectory())11
.forEach(System.out::println);12

}Output:
