Day 117: Readers always are right

On my day 99 post, a reader, Steve, pointed at something that is right. I am using a lot up, down, left and right, so, it is better to create methods for that. I will create them in board class.

public int up(int move){
        int play;
        play=this.getMove(move-this.getBoardSize()+1);
        return play;
    }
    
    public int down(int move){
        int play;
        play=this.getMove(move+this.getBoardSize()+1);
        return play;
    }
    
    public int left(int move){
        int play;
        play=this.getMove(move-1);
        return play;
    }
    
    public int right(int move){
        int play;
        play=this.getMove(move+1);
        return play;
    }
