I am trying to create this game https://en.wikipedia.org/wiki/Conway's_Game_of_Life, however, whenever I am trying to use the printBoard method, I get the following error

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 5 out of bounds for length 5.

How can I fix this issue? Thanks

public class Board {
    final int[][] board;
    final int width;
    final int height;

    public Board(int width, int height) {
        this.width = width;
        this.height = height;
        this.board = new int[width][height];
    }

    public void printBoard() {
        System.out.println("---");
        for (int i = 0; i < height; i  ) {
            String line = "|";
            for (int j = 0; j < width; j  ) {
                if (this.board[i][j] == 0) {
                    line  = ".";
                } else {
                    line  = "*";
                }
            }
            line  = "|";
            System.out.println(line);
        }
        System.out.println("---\n");
    }

    public int countAliveNeighbours(int x, int y) {
        int count = 0;
        count =this.board[x-1][y-1];
        count =this.board[x][y-1];
        count =this.board[x 1][y-1];
        count =this.board[x 1][y];
        count =this.board[x 1][y 1];
        count =this.board[x][y 1];
        count =this.board[x-1][y 1];
        count =this.board[x-1][y];

        return count;
    }

    public void setAlive(int x, int y) {
        this.board[x][y] = 1;
    }

   }

CodePudding user response：

Board initialisation is

 this.board = new int[width][height];

Make it to:-

 this.board = new int[height][width];

or change the loop where you are iterating height with width.
