Fantasy Zoo Manager

Goal: Practice OO modelling in Java (unit tests, no UI)

You have been asked to create a zoo management app so that we can manage our bears, tigers, lions and other animals. The user must be able to add enclosures, add / remove animals, sell animals to other zoos. There should be at least two zoos, and at least three different animal species at each zoo, with different numbers of each species.

Additionally:

• Animals can be fed so that they stay alive.
• Animals cannot be placed in the same enclosure if they would eat one and other.

Homework

Tonight's homework is to think about how you would implement the game of 3 Card Brag (the rules of which can be found here: https://en.wikipedia.org/wiki/Three_card_brag ) in Java. Betting is NOT required.

At this stage we are only asking you to PLAN how you would do this i.e. think about which classes you think you would need, any interfaces you would use etc.

Think about the logic you would need to find the winning player and how to compare hands.

Remember to think about what tests you would need.

Lab / Homework

• Add a new class Chicken which only clucks(), and allow the bear to eat it.
• Add a method that returns the names of all the food in the bears belly (use class names)
• Add a check so that if the bear is intolerant to the food when he eats it, he will throw up this item

Feel free to add other animals for practice. You may want to try adding your own interface(s).

Test Score Block Graph

The Task

Given a set of 20 test scores (each score being out of 100), you are to determine the grade of each score (A,B,C,D, or E).

You then need find number of the scores of each grade as a percentage of the total number of scores e.g. if there are 5 test scores with a grade of B, then this would be 25%.

Finally, you are to display these percentages in the form of a block graph, where each 1% is represented by an asterisk e.g.:
