這篇文章主要介紹“java如何實現聯(lián)機五子棋”的相關知識，小編通過實際案例向大家展示操作過程，操作方法簡單快捷，實用性強，希望這篇“java如何實現聯(lián)機五子棋”文章能幫助大家解決問題。
下面是客戶端運行的效果：
這里是代碼包的結構：
接著我來依次說下這些類所完成的功能
Media包
Media包：主要是放了五子棋的背景圖片和播放音樂的類以及音樂內容
播放音樂這個類是我從室友那拿的，所以我也不是很懂，瞄了一眼是用Applet完成的，只能處理.wav后綴的音樂
Net包
Net包：包含兩個類，細心的小伙伴應該注意到客戶端是沒有主方法的?？蛻舳酥衅鋵嵤前c服務端進行通信的socket的，其中包含一些讀和寫的方法。服務端我采用的是線程池的方法來處理客戶端的請求（線程池這部分我也不是特別了解，用起來和多線程感覺差不多）。
View包
View包：包含四個類，分別是ChessBoard,ChessPanel,Pieces和WhoWin 類
ChessBoard是一個包含Main方法的JFrame,命令面板和棋盤面板都是添加到這個JFrame中的。
ChessPanel是一個棋盤面板，里面完成了如：畫19*19的棋盤線條，加載背景圖片，不停的接收來自服務端的消息并處理（把棋子加到面板），處理每次點擊后添加棋子到面板并發(fā)送棋子到服務器，判斷勝負并且給出提示消息。
Pieces是一個棋子，其中有包含如顏色，棋子半徑，棋子位置和命令（和前面的命令面板配合使用，默認是發(fā)送）等屬性。
WhoWin就是五子棋中判斷誰輸誰贏的部分。每下一步就需要判斷。
播放音樂的類：
