This exercise is about using and defining static classes, methods and instance variables.
The project contains the class ListMethods, which defines two methods FindSmallestNumber and FindAverage. The names should hopefully indicate what they do… Code that tests the class is included in InsertCodeHere.cs.
The class is tested in the traditional way; create an object, and call methods on the object.
1. Modify the ListMethods class such that it becomes a static class. Remember that a static class can only contain static methods.
2. Modify the code in InsertCodeHere.cs, such that it uses the ListMethods class as a static class. The output of running the program should of course be as before.
The project also contains a simple class Car (see the code). We would now like to track how the class is used. More specifically, we wish to track:
*How many objects of type Car have been created
*How many times has the property get method GetLicensePlate been called?
*How many times has the property get method GetPrice been called?
Note that it is the “grand totals” we wish to track, not the number of method calls on each object!
3. Add static instance fields to the Car class, to enable the tracking described above. Increment the value of each variable at the appropriate place in the class.
4. Add a static method that can print out the values of the static instance fields. It could be called PrintUsageStatistics.
5. Test that your additions work, by including some test code in InsertCodeHere.cs. Create some Car objects, call methods on them, and finally call the static method to observe the usage statistics.
