上一篇文章講的是java實現兩人五子棋游戲(二) 畫出棋盤，已經畫好棋盤，接下來要實現控制功能，主要功能：
1）選擇棋子
2）畫棋子
3）判斷勝負
4）交換行棋方
先實現畫棋子part
-------------畫棋子代碼示例如下--------------
首先，定義一個棋子類，這個類有兩個屬性，棋子顏色（0-表示黑色，1-表示白色），是否落子（我計劃用一個二維數組才存儲棋子的落子信息）

package xchen.test.simplegobang; public class chessman { private int color;//1-white，0-black private boolean placed = false; public chessman(int color,boolean placed){ this.color=color; this.placed=placed; } public boolean getplaced() { return placed; } public void setplaced(boolean placed) { this.placed = placed; } public int getcolor() { return color; } public void setcolor(int color) { this.color = color; } } |
接著我們上一部分的畫好棋盤的代碼部分，新增畫棋子的代碼，我用兩個棋子（一白一黑，分別位于棋盤的【8，8】，【7，7】）來檢驗畫棋子的代碼
