Modify a Class Implementation Tips

$$ Accomplish your task incrementally.

$$ In Time$2$

o Create a new instance variable called totalSeconds to keep track of the total number of

seconds from midnight.

o Now start converting the getters and setters starting with getHour$()$ and setHour$().$

Since you need getHour$()$ to complete setHour$()$ start with getHour$().$ getHour$()$ just

returns totalSeconds $/60/60.$ setHour$()$ subtracts out the current value for the hour

and then adds the new value. setHour$()$ looks like the following:

o You should now be able to delete the instance variable hour and when you run

Time$2$Test.java the output should be exactly the same as it was before you made the

changes to getHour$()$ and setHour$().$

o Now do the same thing to getMinute$()$ and setMinute$()$ coming up with the correct

formulas to work with minutes instead of hours. Then delete the instance variable

minute.

o Finally, convert getSecond$()$ and setSecond$()$ and when you are done delete the instance

variable second.

$$ In Time$2$Test.java the only change you are allowed to make is to add a statement at the

beginning of main$()$ to output your name and lab number.
