Check whether a file is a directory in Java

Java 8Object Oriented ProgrammingProgramming

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();
}
