Java Programming: Farm Simulator

Needed the most are: Inheritance, Interfaces, Abstract Classes, and Arraylists. 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 () ;

• Create an Animal Class that will be the base class for all your animals: All animals have some level of hunger from 0-24.
• When an animal is instantiated, it should randomly pick some number of hunger units between 0 and 24. (in the constructor)
• Since it is a small farm all animals have their own name.
• All animals must be able to be fed (decrease their hunger units by 5 when they are fed).
• Animals must increase their hunger as time goes on: create a method that increases their hunger by 1 unit of hunger.
• 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.
• 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.
• You could put this in the constructor: hungerUnits = hungerUnits-(hungerUnits%5);

• 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:

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

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

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

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

  5. Fifth Animal Class: Hunger Level + 2

• 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.

• 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:
