Problem 9: Implement UNIX find command in Java
--------------------------------------------------------------------------------
UNIX find command locates files based on some user-specified criteria and either prints the pathname of each matched object or, if another action is requested, performs that action on each matched object.

It initiates a search from a desired starting location and then recursively traverses the nodes (directories) of a hierarchical structure (typically a tree). find can traverse and search through different file systems of partitions belonging to one or more storage devices mounted under the starting directory.

The possible search criteria include a pattern to match against the filename. By default, find returns a list of all files below the current working directory, although users can limit the search to any desired maximum number of levels under the starting directory.

Write a program to implement the same find command like method in Java. Assume that find method takes two arguments:

a directory name as String, and
the file name pattern as String, that are to be printed

Usage: java JFind |directory| |filename-pattern|
