Add three constructors to the class DigitalClock created in the previous exercise. Give them the following capabilities:

• Set the hour, minute, and second fields to given values

• Set the color field in addition to the previous fields to given values

• Set the dimensions of the digital clock in addition to the previous fields to given values

Create a test driver that allows the user to create either a default instance of a digital clock or an instance in which the user sets all of the fields of the digital clock.
