Determining if a Filename path is a file or a directory

You can solve this problem very easily. What you need to do, just create a File object and pass some file name or a directory in it.

We are using a following methods to solve this problem.

isDirectory(): It checks whether the file is a directory or not.

getAbsolutePath(): It returns the absolute path of a file or directory.

Code of the program is given below:


import java.io.*;



public class FileOrDirectory{

  public static void main(String args[]){

  File directory = new File("Enter any 

 
directory name or file name");

  boolean isDirectory = directory.isDirectory();

  if (isDirectory) {

  // It returns true if directory is a directory.

  System.out.println("the name you have entered 

   is a directory  : "  +  directory);  

  //It returns the absolutepath of a directory.

  System.out.println("the path is "  + 

  
 directory.getAbsolutePath());

  } else {

  // It returns false if directory is a file.

  System.out.println("the name you have

   entered is a file  : " + directory);

  //It returns the absolute path of a file.

  System.out.println("the path is "  +  

    directory.getAbsolutePath());

  }

  }

}

The output of this example is given below:

C:\FileOrDirectory>java FileOrDirectory
the name you have entered is a file : FileOrDirectory
the path is C:\FileOrDirectory\FileOrDirectory
