OOP Tic Tac Toe Draft - based on Elegant Objects by @yegor256

TicTacToe.java

interface Board {
  Board movement(Movement movement);
  Player winner();
}

public static void main() {
  Player black = new Player("Black");
  Player white = new Player("White");
  Board board = new Board(black, white);
  Movement movement = new Movement(black, board).position();
  while(!board.hasWinner()) {
    board = board.movement(new Movement(black, board));
    if(!board.hasWinner()) {
      board = board.movement(new Movement(white, board));
    }
  }
  System.out.println("Congratulations! The winner is: " + board.winner());
}

sounds like a good idea for a talk on OOP ;)
start with procedural for-loops approach and go towards this one
just live coding ;)
