     What difficulty are you having?  Here are a few hints
about possible solution steps:

     - To inspect the names of files and folders contained in
another folder, start with a File object representing the
container and use its list() or listFiles() method:

	File folder = new File("C:\\Users\\siddareddy\\folder");
	for (String name : folder.list())
	    System.out.println(name);
	// ... or ...
	for (File child : folder.listFiles())
	    System.out.println(child);

     - To convert the first part of a file name to a time stamp
(so you can easily compare it to "Yesterday" or "Last week"),
first separate the date-and-time portion from the rest:

	String name
	    = "31-05-2018_10-42-25_rakesh_hike_load_608_output.txt";
	String prefix = "31-05-2018_10-42-25";

... then use a SimpleDateFormat to parse the prefix:

	DateFormat format = new SimpleDateFormat("dd-MM-yy_HH-mm-ss");
	Date stamp = format.parse(prefix);

     If this doesn't help you get started, please tell us more about
the problems you are facing.
