Java实现简单五子棋
小王曾是少年 人气:0本程序适用于java初学者巩固类与对象、事件响应、awt包中各种工具的相关概念以及对逻辑能力的锻炼
需要注意的有：
- ①要加入
java界面的重绘（基本原则） - ②由于玩家需要通过鼠标点击，计算机响应出棋子的位置，但却不能保证每次点击都正中棋盘点位，所以要有一定的误差范围
- ③要保存更新棋盘上的棋子信息，因为棋盘格数是固定的故本例中采取最简单的数组
直接上代码：
分为三个类，同一包下：
package Study0326;
public interface WZQConfig {
/*
* 起始位置X
*/
public static final int START_X = 60;
/*
* 起始位置Y
*/
public static final int START_Y = 60;
/*
* 五子棋盘线条数
*/
public static final int H_LINE = 15;
/*
* 五子棋盘竖线条数
*/
public static final int V_LINE = 15;
/*
* 五子棋盘格子大小
*/
public static final int SIZE = 60;
/*
* 储存棋子的x位置信息
*/
public static final int[][] bx = new int[17][17];
}
