IMPORTANT DEADLINE --->>> 8:00pm EST Sunday April 18th, 2010 -( 8:00pm EST )

Comments are REQUIRED; flow charts and pseudocode are NOT REQUIRED.

Directions

Points

The file must be called <LastFirstWeek5CatMouse.java> (driver program)

[url removed, login to view]

[url removed, login to view] (which extends Mammal)

[url removed, login to view] (which extends Mammal)

Ensure you include ALL files required to make your program compile and run.

I would like to see your .java files only.

If possible, submit all programs as a single .zip file (not required)

Proper coding conventions required the first letter of the class start with a capital letter and the first letter of each additional word start with a capital letter.

Overall Requirements

Write a program that simulates the battle between a cat and mice.

Use this class hierarchy:

Cat

· Kills 1 mouse a day

· Does not reproduce

Mice

· Have a chance to reproduce as long as conditions are met

· Reproduction only happens when mice are over 1 and 1 of each sex is present

Simulation Control

· Simulation continues as long as population is greater than 1 and less than 10

Driver main method should be as shown below: (replacing comment with missing piece)

import [url removed, login to view];

public class LastFirstWeek5CatMouse

{

public static void main(String [] args)

{

cat sylvester = new cat();

ArrayList<mouse> mice = new ArrayList<mouse>();

[url removed, login to view](new mouse());

[url removed, login to view](new mouse());

[url removed, login to view](new mouse());

[url removed, login to view](0).setSex(true);

[url removed, login to view](1).setSex(false);

[url removed, login to view](2).setSex(false);

while ([url removed, login to view]() >1 && [url removed, login to view]() < 10)

{

for (mouse m:mice)

[url removed, login to view]();

[url removed, login to view]();

[url removed, login to view](mice);

[url removed, login to view](mice);

}

//INCLUDE CODE FOR OUTPUT HERE

}

}

Output code should output:

Depending on if the population of mice is greater than or equal 10:

Mice RULE, Cats Drool Mice Population: ## (integer value)

or

Cats RULE, Mice Drool Cat Weight (in mice): ##.## (double value, 2 decimal places)

[url removed, login to view] class

Instance variables:

name (string)

age (integer)

weight (double)

isMale (Boolean)

mammal constructor : (default constructor)

Set age to 1.

grow method :

Increases age of mammal by 1.

Accessor / mutator methods for each instance variable above:

Set or returns values as appropriate for data type specified.

[url removed, login to view] class

eat method: (receive mouse arraylist as argument)

Randomly removes a mouse from the population 70% of the time and increases cat weight by the chosen mouse weight. Only increase weight if mouse is removed/eaten. (See chapter 5, lottery example, for random example)

grow method:

Set the cats age to the current age plus 1. (use accessor/mutator methods)

[url removed, login to view] class

mouse constructor: (default constructor)

Randomly choose sex and assign to isMale as appropriate.

Set age to 1.

Set weight to 1.

grow method:

Increase age of mouse by 1 and weight of mouse by 1% of current weight.

mate method: (static method, receive mouse arraylist as argument)

Randomly choose 2 mice objects from arraylist and if conditions are correct, proceed with mating.

Successful mating conditions are:

· 1 male, 1 female mouse

· Both mice older than 1 day

If successful mating, randomly create between 0-4 mice and append to arraylist received as argument.

Sample session (requires no user input):

Mice RULE, Cats Drool Mice Population: 11

Press any key to continue . . .

Cats RULE, Mice Drool Cat Weight (in mice): 2.03

Press any key to continue . . .

Mice RULE, Cats Drool Mice Population: 10

Press any key to continue . . .

Cats RULE, Mice Drool Cat Weight (in mice): 2.05

Press any key to continue . . .

As always, you should:

* Limit your use of class variables and instance variables – only use them if appropriate.

* Use appropriate modifiers for your methods. The modifiers we've discussed are private, public, static, and final.

* Use helper methods if appropriate.

* Follow the Java Coding Styles Document including comments and style

* Mimic the sample session precisely.
