前言

做完了中國象棋的幾部分，可能前面有些地方敘述不清，故寫一篇代碼合集，可以對照發(fā)現(xiàn)是否有寫錯的地方。共分為5個文件，分別為??DrawUI.java??,??Listener.java??,??init.java??,??BlackWin.java??,??RedWin.java??.其中前三個文件在前面的文章中均有介紹，后兩個是勝利后分別出來的彈窗，因簡單故不再多加敘述。

請不要直接復制粘貼，這樣沒有任何意義！

另：代碼與棋盤圖片是配套的，如果使用自己的棋盤圖片不行的話就改一下init里面的數據。

關注微信公眾號：圖靈完備，回復中國象棋即可獲得圖片及代碼資源。
