以下是服务器端对应的具体代码示例:

```
上述代码实现了服务器端的功能,包括监听客户端连接、处理游戏逻辑、发送游戏状态更新等。其中,`acceptPlayers()` 方法用于等待两个客户端连接,并向客户端发送欢迎消息;`playGame()` 方法用于处理游戏逻辑,包括等待客户端下棋请求、检查请求的合法性、更新游戏状态和发送游戏状态更新消息等。在 `playGame()` 方法中,使用 `BufferedReader` 和 `PrintWriter` 实现了服务器端与客户端的通信。 `isValidMove()` 方法用于检查下棋请求是否合法,`isWinner()` 方法用于检查当前玩家是否获胜,`isBoardFull()` 方法用于检查棋盘是否填满,`getBoard()` 方法用于获取当前的棋局状态。在 `main()` 方法中,创建了一个 `TicTacToeServer` 对象并调用其方法以启动服务器。
