(The Time class)
Design a class named Time.
The class contains:
- The data fields hour, minute, and second that represent a time.
- A no-arg constructor that creates a Time object for the current time. (The values of the data fields
will represent the current time.)
-A constructor that constructs a Time object with a specified elapsed time since midnight, January
1, 1970, in milliseconds. (The values of the data fields will represent this time.)
-A constructor that constructs a Time object with the specified hour, minute, and second.
- Three getter methods for the data fields hour, minute, and second, respectively.
-A method named setTime (long elapseTime) that sets a new time for the object using the
elapsed time. For example, if the elapsed time is 555550000 milliseconds, the hour is 10, the
minute is 19, and the second is 10.
Draw the UML diagram for the class and then implement the class.
Write a test program that creates two Time objects (using new Time (), new Time(555550000),…
