The program to recursively find a file in Display 11.11 stops searching when the first match is found. Modify the program so that if there are multiple files with the same name in different directories, then all matching files are found and output. The simplest way to do this is to output all matches in the recursive method with a print statement. For a more challenging version, modify the method to return an array of Strings containing the pathnames of all matching files. It can return null or an empty array if there are no matches. Feel free to create additional helper classes if needed (e.g., to manage the number of items in the array of Strings). In Chapter 14 , we will introduce ArrayLists , which make it easier to create an array-like structure with an arbitrary number of entries.
