JAVA PROGRAMMING

-You must create a very simple farm simulation.

-The simulation will run in a loop and call a method that indicates the passage of time.

-YOU MUST USE A GENERIC CONTAINER such as ArrayList.

-The Generic it has must be some form of the base class ANIMAL such as: ArrayList farm = new ArrayList () ;

1. Create an Animal Class that will be the base class for all your animals: All animals have some level of hunger from 0-24.

2. When an animal is instantiated, it should randomly pick some number of hunger units between 0 and 24. (in the constructor)

3. Since it is a small farm all animals have their own name.

4. All animals must be able to be fed (decrease their hunger units by 5 when they are fed).

5. Animals must increase their hunger as time goes on: create a method that increases their hunger by 1 unit of hunger.

6. In the loop example below tick() is used since the method relates to the virtual passing of time. While in this case all that happens is the hunger level increases other simulators might have much more complex effects.

7. When printed an animal should indicate. The animals name, the type of the animal and the animals hunger level: Ely the cow is very hungry.

8. If we are never going to instantiate an Animal directly what type of class could we make it? Explain. Put your answer in the comments at the bottom of your report.

Note: It is possible that when you run the simulation it will loop infinitely*. Can you explain why? Put your answer in the comments at the bottom of your report

* For larger sets of animals this would almost always happen.

You could put this in the constructor:

hungerUnits = hungerUnits-(hungerUnits%5);

What does this do? Why does this stop infinite loops?

Hunger Level Chart

Hunger Units	Hunger Level Name	Hunger Level
0-4	Full	0
5-9	Peckish	1
10-14	Hungry	2
15-19	Very Hungry	3
20-24	Starving	4

9. Create 5 subclasses of farmyard animals:

a. Each animal should also speak based on what type of animal it is and how much they speak should change with their hunger level. A cow might moo

b. The calculation for the times speaking will be different for each subclass

c. The calculation for the first five animal subclasses should be:

i. First Animal Class: (Hunger Level + 1) * 2

ii. Second Animal Class: (Hunger Level + 1)

iii. Third Animal Class: ((Hunger Level / 2) + 1) * 2

iv. Fourth Animal Class: (Hunger Level * 3)

v. Fifth Animal Class: Hunger Level + 2

10. Create a class with a main method

a. that instantiates 2 of each or your animals and put them in an ArrayList. Sort the animals by their hunger level (most hungry to least hungry).

b. Allow each animal to speak, print it out and then feed it if it is not full.

Continue this process until all of them are full.

11. Implement a sleeping feature.

All animals have a 10 percent chance of falling asleep when they are fed.

Side Effects of sleeping:

1. Animals that are asleep do not decrease their hunger units when fed.

2. Animals that are asleep Snore when then speak instead of their normal vocalization.

3. Animals wake up if their Hunger Level changes

The Output from the simulator might look something like this:

public static void main(String[] args) { ArrayList farm = new ArrayList(); for (Animal animal: farm) { animal.tick(); animal.feed(); System.out.println(animal.speak()); System.out.println(animal); Feeding 1 cluck cluck cluck cluck Yellow the Chicken is Very Hungry woof woof woof Teddy the Dog is Hungry moo moo Jackie the Cow is Peckish cluck cluck Dolly the Chicken is Peckish moo Jenny the Cow is Full woof Fido the Dog is Full Feeding 2 cluck cluck cluck Yellow the Chicken is Hungry woof woof Teddy the Dog is Peckish moo Jenny the Cow is Full moo Jackie the Cow is Full cluck Dolly the Chicken is Full woof Fido the Dog is Full Feeding 3 cluck cluck Yellow the Chicken is Peckish woof woof Teddy the Dog is Peckish moo moo Jenny the Cow is Peckish moo Jackie the Cow is Full cluck Dolly the Chicken is Full woof Fido the Dog is Full Feeding 4 cluck cluck Yellow the Chicken is Peckish moo moo Jackie the Cow is Peckish cluck Dolly the Chicken is Full woof Fido the Dog is Full woof Teddy the Dog is Full moo Jenny the Cow is Full Feeding 5 cluck cluck Dolly the Chicken is Peckish woof woof Fido the Dog is Peckish woof Teddy the Dog is Full moo Jenny the Cow is Full cluck Yellow the Chicken is Full moo Jackie the Cow is Full Feeding 6 woof Teddy the Dog is Full moo Jenny the Cow is Full cluck Yellow the Chicken is Full moo Jackie the Cow is Full cluck Dolly the Chicken is Full woof Fido the Dog is Full public static void main(String[] args) { ArrayList farm = new ArrayList(); for (Animal animal: farm) { animal.tick(); animal.feed(); System.out.println(animal.speak()); System.out.println(animal); Feeding 1 cluck cluck cluck cluck Yellow the Chicken is Very Hungry woof woof woof Teddy the Dog is Hungry moo moo Jackie the Cow is Peckish cluck cluck Dolly the Chicken is Peckish moo Jenny the Cow is Full woof Fido the Dog is Full Feeding 2 cluck cluck cluck Yellow the Chicken is Hungry woof woof Teddy the Dog is Peckish moo Jenny the Cow is Full moo Jackie the Cow is Full cluck Dolly the Chicken is Full woof Fido the Dog is Full Feeding 3 cluck cluck Yellow the Chicken is Peckish woof woof Teddy the Dog is Peckish moo moo Jenny the Cow is Peckish moo Jackie the Cow is Full cluck Dolly the Chicken is Full woof Fido the Dog is Full Feeding 4 cluck cluck Yellow the Chicken is Peckish moo moo Jackie the Cow is Peckish cluck Dolly the Chicken is Full woof Fido the Dog is Full woof Teddy the Dog is Full moo Jenny the Cow is Full Feeding 5 cluck cluck Dolly the Chicken is Peckish woof woof Fido the Dog is Peckish woof Teddy the Dog is Full moo Jenny the Cow is Full cluck Yellow the Chicken is Full moo Jackie the Cow is Full Feeding 6 woof Teddy the Dog is Full moo Jenny the Cow is Full cluck Yellow the Chicken is Full moo Jackie the Cow is Full cluck Dolly the Chicken is Full woof Fido the Dog is Full
