Subtracter Single Method

Geoffrey Challen // 2021.2.0

Create a public class called Subtracter. Subtracter should store a single int in a private field and provide a public setValue method that sets the stored int to the passed value. (You can initialize the stored value to 0.) It should also provide a public method called subtract. subtract should accept an int parameter, subtract it from the stored value, and return the updated value. Do not implement getValue.
