FindFile Class Interface FindFile(int maxFiles): This constructor accepts the maximum number of files to find. void directorySearch(String target, String dirName): The parameters are the target file name to look for and the directory to start in. This will save the file locations (i. e., file path, starting from dirName) in some private class data structure. int getCount(): This accessor returns the number of matching files found String[] getFiles(): This getter returns the array of file locations, up to maxFiles in size.

Java program for the problem is explained below

Explanation:
