- Use the debugger to examine the clock-display project. Set breakpoints in the ClockDisplay constructor and each of the methods, and then singlestep through them. How do you feel about the way it's behaving? Have you gained any fresh insights as a result of this?

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_forward2.

Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value.
