Define a class named TimeSpan. A TimeSpan object stores a span of time in hours andminutes (for example, the time span between Monday 8AM and Wednesday 10:30AM is50 hours, 30 minutes). Each TimeSpan object should have the following public methods:00000TimeSpan (hours, minutes)Constructs a Timespan object storing the given time span of minutes and seconds.add (hours, minutes)Adds the given amount of time to the current time span (e.g. 2 hours, 15 min + 1 hour, 45 min = 4 hours).Assume that the arguments are valid: the hours are non-negative, and the minutes are between 0 and 59.add (timespan)Adds the given amount of time (stored as a time span) to the current time span.getTotalHours ()Returns the total time in this time span as the real number of hours (such as 9.75 for 9 hours, 45 min).tostring ()Returns a string representation of the time span of hours and minutes, such as "28h4 6m".The minutes should always be reported as being in the range of 0 to 59. That means that you may have to"carry" 60 minutes into a full hour. For example, consider the following code:TimeSpan tl = new TimeSpan (3, 45);System.out.println (tl + " is " + t1.getTotalHours () +t1.add (2, 30);System.out.println (tl +TimeSpan t2t1.add (t2);System.out.println (t1 +hours");" is " + tl1.getTotalHours () + " hours");= new TimeSpan (0, 55);is+ t1.getTotalHours () + " hours");This code creates a Timespan object and adds three different times to it. The output should be:3h45m is 3.75 hours6h15m is 6.25 hours7h10m is 7.166666666666667 hoursNotice that the second time is not 5 hours, 75 minutes, although that's what you'd get by just adding values.

Question

Define a class named TimeSpan. A TimeSpan object stores a span of time in hours and
minutes (for example, the time span between Monday 8AM and Wednesday 10:30AM is
50 hours, 30 minutes). Each TimeSpan object should have the following public methods:
00000
TimeSpan (hours, minutes)
Constructs a Timespan object storing the given time span of minutes and seconds.
add (hours, minutes)
Adds the given amount of time to the current time span (e.g. 2 hours, 15 min + 1 hour, 45 min = 4 hours).
Assume that the arguments are valid: the hours are non-negative, and the minutes are between 0 and 59.
add (timespan)
Adds the given amount of time (stored as a time span) to the current time span.
getTotalHours ()
Returns the total time in this time span as the real number of hours (such as 9.75 for 9 hours, 45 min).
tostring ()
Returns a string representation of the time span of hours and minutes, such as "28h4 6m".
The minutes should always be reported as being in the range of 0 to 59. That means that you may have to
"carry" 60 minutes into a full hour. For example, consider the following code:
TimeSpan tl = new TimeSpan (3, 45);
System.out.println (tl + " is " + t1.getTotalHours () +
t1.add (2, 30);
System.out.println (tl +
TimeSpan t2
t1.add (t2);
System.out.println (t1 +
hours");
" is " + tl1.getTotalHours () + " hours");
= new TimeSpan (0, 55);
is
+ t1.getTotalHours () + " hours");
This code creates a Timespan object and adds three different times to it. The output should be:
3h45m is 3.75 hours
6h15m is 6.25 hours
7h10m is 7.166666666666667 hours
Notice that the second time is not 5 hours, 75 minutes, although that's what you'd get by just adding values.

Design a class called Stopwatch. The job of this class is to simulate a stopwatch. It should provide two methods: Start and Stop. We call the start method first, and the stop method next. Then we ask the stopwatch about the duration between start and stop. Duration should be a value in TimeSpan. Display the duration on the console. We should also be able to use a stopwatch multiple times. So we may start and stop it and then start and stop it again. Make sure the duration value each time is calculated properly. We should not be able to start a stopwatch twice in a row (because that may overwrite the initial start time). So the class should throw an InvalidOperationException if its started twice. 1
