Write a class called counter that represents a simple tally counter, which might be used to count people as they enter a room. The Counter class should contain a single integer as instance data, representing the count. Write a constructor to initialize the count to zero. Write a method called click that increments the count and another method called getCount that returns the current count. Include a method reset that resets the counter to zero. Finally, create a driver class called CounterTest that creates two Counter objects and tests their methods.
