这篇文章主要介绍了利用Java实现小程序简单五子棋,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,下面来看具体实现吧
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]; }
