In this section, you will learn how to determine a file or directory exit or not.

Determining if a File or Directory Exist

This is a very simple problem. You just have to determine whether a file or directory exists or not. If it exists it returns true otherwise in the else condition, it retunes vice-versa.

The following program creates an object of File class and checks whether the given file exists or not by using exists() method of the class.

We have used following methods:

exists(): It checks whether the file or directory denoted by this pathname exists or not.

Code of this program is given below:


import java.io.*;



public class FileOrDirectoryExists{

  public static void main(String args[]){

  File file=new File("Any file name or 

   directory whether exists or not");

  boolean exists = file.exists();

  if (!exists) {

  // It returns false if File or directory does not exist

  System.out.println("the file or directory 

  you are searching does not exist : " + exists);

  

  }else{

  // It returns true if File or directory exists

  System.out.println("the file or 

  directory you are searching does exist : " + exists);

  }

  }

}

The output of the program is given below:

C:\java>java FileOrDirectoryExists
the file or directory you are searching does not exist : false
