CPS206 Iterative In Class Examples
This repository is for students of CPS206 at John A Logan College in the Spring 2017 semester to have in class examples correctly completed for them.

This repository will follow semantic versioning. This means as we continue with lectures, I will update the repository with either minor or micro tag updates. Each version will update this read me about the changes we accomplished in that lecture.
The following are the versioning changelogs.
We identified that the toString methods are repetitive and that we could use polymorphism to allow us to stay DRY.
Because of this, we need to do a lot of refactoring. First, we need to create a Liquid. From that Liquid, we need create Beverage which extends Liquid, and Soda and Beer extend Beverage. But because Water is not only a Beverage, we need to move that class out of beverage and into the liquid package. Maybe later Water will identify which package is correct for it, but until then, moving it into Liquid is satisfactory.
We also decided to change our beverages so we can keep using declarative accessor methods, e.g. sodaBottle.getSoda() vs sodaBottle.getLiquid(). In the process, we discover that WaterBottle's constructor cannot pass a Liquid to a Beverage because a Liquid is not a Beverage.
This forces us to move WaterBottle out of Beverage. But now we have an issue of repetition that needs to be solved. This issue will be an extra credit assignment due Friday, March 3, 2017 at midnight. Simply for the repository and once you have made the changes, do a pull request. Those correct solutions will be given 5 points.
We demonstrated that we can polymorph into bottles and that the latest toString method would resolve and that each child class can use getCapacity. Then we introduced the HandSanitizerBottle. This led us to the conclusion that we needed to refactor some to prevent us from drinking hand sanitizer on accident. This version reminds us what we did.
In this version, we introduced the basic usage of polymorphsim. We create a basic main driver to put a bunch of bottles into a collection.
We decied that Bottle should be be intantiated, so we set the class to abstract
We realized we had duplicate code. Because of so, we decided to abstract out those features and put them into a parent class named Bottle, and extend Bottle into our 3 bottle-typed classes.
This version simply adds the toString methods which were required.
Adds base objects of SodaBottle, BeerBottle, WaterBottle with no inheritance. Also provides empty objects of Soda, Beer, and Water for has-a relationships.
Initial - no code.
