CHALLENGE:

Write a class named Averager containing:
An instance variable named sum of type integer , initialized to 0.
An instance variable named count of type integer , initialized to 0.
A method named getSum that returns the value of sum .
A method named add that accepts an integer parameter . The value of sum is increased by the value of the parameter and the value of count is incremented by one.
A method named getCount that accepts no parameters . getCount returns the value of the count instance variable , that is, the number of values added to sum .
A method named getAverage that accepts no parameters . getAverage returns the average of the values added to sum . The value returned should be a value of type double (and therefore you must cast the instance variables to double prior to performing the division).
