Question

The project CreateDirectoriesDemo is included with the files for this chapter as a zipped file. rewrite the program so that it asks the user for the location where the new directories are to be created, and then asks the user to enter, one at a time, the relative path names of the directories it should create.

Amended additional details to the above abstraction of the requirements.

1. The application should be multiplatform adaptive. This means that it should work on an Apple, Linux, and Windows OS. A Windows OS permits the use of drive letters and backslashes. The application should be able to create folders/directories that include drive letters for the additional drives other than the C:\ Drive
   
   
2. The name of the assignment is “Create a Directory Path from User Input”. A path may include the creation of multiple hierarchical layers of directories/folders. The program should identify a path that contains multiple layers of folders and created the appropriate folder levels.
   
   
3. The use should be able to enter multiple path entries during a single program execution. The program should provide away for the user to either enter the number of items being entered or have a value that indicates the end of the input
   
   
4. The Interface of the program should explain clearly to the user what to input at every data entry input point in the program

/* CreateDirectoriesDemo.java

* CSCI 112 - Spring 2014

*

* The software in this example creates a set of folders (directories).

* It is intended as an example for CSCI 112.

*

* The directory which will contain the new set of directories is identified in

* line 23 of this code as "c:\", the root directory on most Microsoft Windows

* systems. This can be changed to place the new set of directories elsewhere.
