本文實例講述了java實現的中國象棋遊戲代碼，分享給大家供大家參考，具體代碼如下
一、實踐目的：
1.鼠標點擊、拖動等事件的應用與區別
2.棋譜文件的保存與讀取
3.完善象棋的規則。
二、實踐內容：
中國象棋歷史悠久，吸引了無數的人研究，現對中國象棋的對戰和實現棋譜的製作做如下的設計和說明，供大家參考學習。
1、機機對弈，紅方先手。在符合規則的情況下拖動棋子到目的地，松鼠標落子。
人人對弈圖
2、製作棋譜，選擇製作棋譜菜單後，對弈開始，並記錄了下棋過程。
選擇“製作棋譜”菜單
棋譜製作完畢紅方勝出
一方勝出後彈出勝利消息對話框。點擊確定後，選擇“保存棋譜”菜單，彈出保存文件對話框。
保存棋譜對話框
3.演示棋譜，選擇演示棋譜菜單後，彈出打開對話框，選擇保存好的棋譜，開始演示。
演示棋譜對話框
演示棋譜過程（自動和手動兩種）

1.理解8個文件，沒有太複雜的代碼。
2.理解鼠標的MouseListener,MouseMotionListener兩個接口的區別，五子棋的實現不需要MouseMotionListener。
3.使用LinkedList記錄棋譜的方法。
