Check whether a file is a directory in Java

The method java.io.File.isDirectory() checks whether a file with the specified abstract path name is a directory or not. This method returns true if the file specified by the abstract path name is a directory and false otherwise.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.io.File; public class Demo {    public static void main(String[] args) {       try {          File file = new File("demo1.txt");          file.createNewFile();          System.out.println("Is directory? " + file.isDirectory());       } catch(Exception e) {          e.printStackTrace();       }    } }

The output of the above program is as follows −

Output

Is directory? false

Now let us understand the above program.

The method java.io.File.isDirectory() checks whether the file is a directory or not and the boolean value that is returned by the method is printed. A code snippet that demonstrates this is given as follows −

try {    File file = new File("demo1.txt");    file.createNewFile();    System.out.println("Is directory? " + file.isDirectory()); } catch(Exception e) {    e.printStackTrace(); }
