Java GUI Game of Life (and Death)




D Assignment 1: Game of Life (and Death);* If the cell is Empty then * If it is adjacent to at least two Foods, * it will become Food next turn *;Otherwise it will stay as it was. * * If the cell is a Grazer then * If the Grazer is overcrowded or starved *;then it will die next turn. * Otherwise it will stay as it was. * * If the cell is a Food then * If it is next to at;least 2 Grazers * then it will become a Grazer next turn * Otherwise it will stay the same;The Skeleton;On the next few slides I will go through the Skeleton;? The Livable interface;? The World class, in which you put your code;? The LifeAndDeath class, in which you also put code;? The VisualTest class, which runs a visualiser just for your entertainment.;please see the attached skeleton code;Summary: Write a program to simulate a population of grazers and food in a simple 2D world;similar to Conway?s classic Game of Life. For the sake of this assignment, food and grazers are both;creatures. This is an example of using cellular automata.;Each tick of the clock, the next state of the cell will be determined by its current state and the states;of its neighbours, according to the following rules;1. If the cell is EMPTY;If it is adjacent to at least two Foods, it will become Food next turn;Otherwise it will stay as it was.;2. If the cell is a Food;If it is next to at least two Grazers then it will become a Grazer next turn, Otherwise it will stay as;it was.;3. If the cell is a Grazer;If the Grazer is overcrowded or starved then it will die next turn (and the cell will become empty);Otherwise it will stay as it was.;Overcrowded means there aremore than 3 adjacent cells of the same kind as this one.;Starved means, for a predator, that there is no food in any adjacent cell.;We will represent food with dots ?.? and grazers with ?@?. Here?s an example of what you might see if;you run the Visualiser with your (correct) code;The programmust be called LifeAndDeath.;The program must have the class which contains the main method, and another;class file called which implements the Livable interface. You must put all your own;code (not the Livable interface) into a package called assignment1.;The World class must have a constructor that takes as its arguments the size of the grid, the probability;(as a double) of each cell initially containing food, and the probability (as a double) of each cell;initially containing a grazer, like this;1 public World (int size, double probFood, double probGrazer);2 //... fill in this;3 };Do not change the Livable interface in any way.;Youmay add any other methods you like to your program though.;The programmust be able to be run as follows;java LifeAndDeath 25 0.1 0.2 100;Which would create a 25?25 grid of cells, and each cell would have a probability of 0.1 of being a;grazer or of 0.2 of being food (so probability of 0.7 of being empty). The program should run with the;above arguments for 100 ticks of the clock or until everything dies.;The LifeAndDeath program should print out the grid as above with each grid on a new line (not;side by side as I showed in the last part of the example).;If the program is given another argument, the string ?summary? as the last String, then it should;only print out the total number of creatures after each tick of the clock, not the whole grid.;*marking;The marking will be partly by automatic testing of the methods you made to implement the Livable;interface, and partly by hand.;The hand-marking criteria are the same as for the Tasks;Clarity up to 1 mark for good clear layout, sensible variable and method names, and good commenting;Design up to 2 marks for the overall design of how your methods relate to each other, their logic, effective;code re-use, and appropriate use of access modifiers public, private and protected;Error handling up to 2 marks for effectively dealing with run-time errors that could arise through exception;handling and checking for ?corner cases? (e.g. checking coordinates are valid);The auto-marking criteria are;Unit testing up to 5 marks for testing the methods in Livable, implemented in your World class..............................................................................................................;Testing The automatic testing will test each method you have to implement, and will test that your;World constructor works correctly. It will call the methods given in the skeleton code and compare the;return values with what is expected.;Automatic testing is worth 5 marks for this Assignment
