JAVA - Simple exercise, BUT PLEASE READ all the instructions in the photo first.

Write a class named Averager containing: An instance variable named sum of type int, initialized to 0. . An instance variable named count of type int, initialized to 0. A method named getSum that returns the value of summ .A method named add that accepts an int 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)
