In this tutorial we will create a Number class that will tell you when a value is really set, how to unset or reset the Number value, even how to Enable and Disable it so it is taken into account when it is added to another number or to any other Integer/Double, as well as adding its value to an array. In the end, you will be able to expand or modify this fun and helpful class it to fit your own purposes.
