Write a Java program to check if a file or directory specified by pathname exists or not.

Sample Solution:

Java Code:

import java.io.File;
public class Exercise3 {
       public static void main(String[] args) {
        // Create a File object
        File my_file_dir = new File("/home/students/xyz.txt");
         if (my_file_dir.exists()) 
           {
            System.out.println("The directory or file exists.\n");
           } 
         else
          {
            System.out.println("The directory or file does not exist.\n");
          }
       }
  }

Sample Output:

The directory or file does not exist.
