java五子棋小游戏实现代码

之前学完java基础课程，试着简单做了一下java的一个五子棋小游戏，记录下来。

由于直接用的java库中的一些基本控件写的一个GUI，并没有做过多优化，感觉比较丑下面是界面展示：

黑子先行，但是我这边简化规则，并没有考虑黑子先行的一些禁手。

下面直接贴代码

我把五子棋界面的一些常量都定义在了这个接口类中，包括棋盘的起始坐标，棋盘线的间距和棋子半径

public interface constant { int[][] chessLocation = new int[15][15]; static final int x = 50; //左上角位置 static final int y = 50; static final int LN = 15; //棋盘一些常量 static final int R = 45;}实现类

接口

这个类中继承了 constant、MouseListener、ActionListener三个接口

其中：

函数

show()绘制窗口基本框架paint()绘制棋盘网格线和棋子IsWin()判断输赢的基本逻辑mouseClicked()获取鼠标位置，判断棋子落点等actionPerformed()判断鼠标点击哪个按钮（开始游戏or认输or悔棋）执行相应操作

其中比较有趣的是五子棋判赢方式，假设棋盘大小15*15，则我只需要判断正中间的13*13d的格子，向两边扩展，判断是否五子连珠。

具体说明代码里都有注释，不多赘述。

public class Main_game { public static void main(String[] args) {game_logic start=new game_logic();start.ShowUI(); }}总结

实现了五子棋小游戏的基本功能，但是略感粗糙，细节不足。对于基本控件调用一学就会，做一个小的游戏demo这是对流程控制和操作逻辑的训练很有效的一种方式。之前看了别人的代码觉得简单，但是自己写的时候往往逻辑流程难以连续，思维混乱，有些过程只有自己写了才知道其中的坑。
