       //variable to store file path
       String path;
      
       Scanner sc = new Scanner(System.in);
      
       //prompt for file path
       System.out.print("Enter file path: ");
      
       //reading file path from user
       path = sc.next();

       //if function filepath returns true
       if(filepath(path))
       {
           //prints message
           System.out.println("File Loaded");
       }

       else
       {
           //prints message
