Homework Assignment #$2$

Classes and Objects

Problem:

Implement a class named Time. The class should contain:

The data fields for hour, minute, and second that represent a time.

A no$-$argument 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 $1,2000,$ 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 $10.$

Then implement a test class named Driver. In this test class create two Time objects $($using new Time$()$ and new Time$(555550000))$ and displays their hour, minute, and second in the format

hour:minute:second

e$.$g$.10$:$19$:$10$

Hint: For the no$-$argument constructor, the current time can be obtained using System.currentTimeMillis$().$ The other two constructors will extract the hour, minute, and second from the elapsed time.
