Assignment A Recursive Directory Search Utility for Windows This assignment combines recursion, looping and advanced file handling in a practical application for the Windows operating system's file structure. 60+ points See Canvas fordue date This assignment asks you to create a Java program that brings recursion, looping, file handling techniques and (optionally) advanced file date processing together in a useful Windows application. Your program will prompt the user for search criteria and will then 'crawl through a directory together with its subdirectories looking for files that qualify. Results of the search are displayed. Your program should search for files: By name (without an extension -e.g. MyTextFile) By extension name (e.g. java) By content (e.g. Math.sqrt) By modification date (optional extra credit-see below) Notes: The above criteria for searching may be combined in any form (see example runs below.) A valid initial path will always be entered other criteria are optional. You should allow the user to find file name entries regardless of upper/ower case characters in the file and extension names. Searching for content, however, should be case sensitive. The count of qualifying files should be displayed (see example output.) Your class (and your corresponding java file) should be named as follows: o MySearch
