Java实现小程序简单五子棋

133 阅读 0 评论 88 点赞

我是靠谱客的博主搞怪日记本，最近开发中收集的这篇文章主要介绍Java实现小程序简单五子棋，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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];
}
