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).
