Code in Java please,

*Do not use CharToArray*

Please explain how you implemented the code so I have a better understanding

Code uses the rules of Conway's Game of Life

In case you are not familiar with Conways Game of Life, please visit the following page for full details of all rules: https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life. The traditional game of life is played on a flat board (2D array). Your mission is that, given any configuration of a game-of-life, your implementation should allow any user to initialize the 2D array with any population and make it evolve over any given number of time steps.

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 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) o 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:

o 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. o 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.

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:

public class GameOfLife {

if (previous[i][j] == 0 && neighbors == 3) board[i][j] = 1; else if (previous[i][j] == 1) { if (neighbors > 3 || neighbors
