o What are you asked to do? You have 3 main tasks to complete in this lab. 1/ You are first going to design a new user-defined type GameOfLife (defined in a java file called GameOfLife.java). This new type is described as follows: (highlighted is what you have to complete) Attributes: o Size: int o Board: int[][] + this is a square board, same number of rows and columns o Previous: int[][] this 2D array will store a copy of the game of life board. Constructors: o Default constructor: Given to you o Constructor that takes a size as input (this will be the number of rows as well as the number of columns of your board and previous) Constructor that take a 2D array as an input (its size will be the size of the board and previous; its content is to be copied into previous) Getter: o getBoard returns the current board oneStep: o Takes no parameter and is a void method O It consists in transforming the current board into its next shape (board at next time stamp). neighbors: Takes two indices (representing a row index and a column index). o Computes the number of neighbors the corresponding cell on the board has. evolution: o Takes an integer n, which represents the number of evolution steps we need to conduct. Transforms the board into the board after n steps of evolution (i.e., n successive calls to oneStep). Note: you can use more methods (as helper methods for the above methods). However, you need to stick at least to the ones above. 2/ You have to test that your implementation of the game of life is correct. You are expected to do so using JUnit testing, in a file called GOLTester.java. In this file, you have to test the following class methods of the GameOfLife type (5 tests at least per method): neighbors(int, int) oneStep) evolution (int) In particular, you should test the behavior of your two versions of the game of life on at least the following boards: 3/ You can see that there are two methods oneStep in the file GameOfLife.java. Explain what property of OOP describes this situation. What should you turn in? You should submit your 2 java files: GameOfLife.java and GOLTester.java. o What are you asked to do?
