Chapter 5, Problem 27P

Program Plan Intro

Recursive method with calling signature

Program plan:

• Create a class FindFile.
  • In find() method,
  • Check whether the list is not “null”. If yes,
    • The for loop executes until the list. If yes,
      • Check whether the directory is there in the list. If yes,
        • Call recursively find() method to find path from the file name in the list.
      • Otherwise, check whether the given file name is equal to the filename in the list. If yes,
        • Fetch the parents file of the given file name and then display it.
  • In main() method,
    • Create an object for FindFile class.
    • Read the input file name and directory name from the user.
    • Call the find() method to find the path of the file name and then display it.
