The new method should make a Date object's day, month, and year value change to the next day. In other words, add one day to the object's current date. Do not use any part of the built-in DateTime class, but you may want to use the DaysInMonth() method from the Date class. Examples: • If the Date object stores the date 12/31/2021, then after calling your method it should store the date 1/1/2022 • If the Date object stores the date 2/28/2022, then after calling your method it should store the date 3/1/2022 As noted in the common instructions, you only need to turn in your new method, not the entire Date class.arrow_forward
