 * Create a class called Date212 to represent a date. It will store the year,
 * month and day as integers so you will need three private instance variables.
 * One constructor should be provided that takes a String representing the date
 * in yyyy mm dd format. The constructor should use the substring method of
 * class String to pull out the month, day and year, parse them as integers put
 * them in the instance variables. The Date212 class should have the usual set
 * and get methods, and equals, compareTo and toString methods. The toString
 * method should print the date in “mm dd, yyyy” format (for example, 20171002
 * would be returned as “October 2, 2017”.
