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. (Thevalues of the data fields will represent the current time.)■■ A constructor that constructs a Time object with a specified elapsed timesince midnight, January 1, 1970, in milliseconds. (The values of the datafields 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 theobject using the elapsed time. For example, if the elapsed time is 555550000milliseconds, the hour is 10, the minute is 19, and the second is 10.Draw the UML diagram for the class then implement the class. Write atest program that creates three Time objects (using new Time(), newTime(555550000), and new Time(5, 23, 55)) and displays their hour,minute, and second in the format hour:minute:second.
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
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 then implement the class. Write a
test program that creates three Time objects (using new Time(), new
Time(555550000), and new Time(5, 23, 55)) and displays their hour,
minute, and second in the format hour:minute:second.
