标签：java,五子棋

本文实例为大家分享了Java实现五子棋游戏的具体代码，供大家参考，具体内容如下

学习目的：熟悉java中swing类与java基础知识的巩固.(文末有源代码文件和打包的jar文件)

效果图：

思路：**1.首先构建一个Frame框架，来设置菜单选项与按钮点击事件。

MyFrame.java文件代码如下

package StartGame;

import javax.swing.ButtonGroup;
import javax.swing.Icon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JOptionPane;
import javax.swing.JRadioButtonMenuItem;

import java.awt.Color;
import java.awt.Component;
import java.awt.Container;
import java.awt.Graphics;
import java.awt.Toolkit;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

//窗体框架类
public class MyFrame extends JFrame {
// static boolean canPlay1 = false;判断是否可以开始游戏
final MyPanel panel = new MyPanel();

public MyFrame() {

// 设置窗体的大小并居中
this.setSize(500, 600); // 设置窗体大小
this.setTitle("五子棋游戏"); // 设置窗体标题

int width = Toolkit.getDefaultToolkit().getScreenSize().width;// 获取屏幕的宽度
int height = Toolkit.getDefaultToolkit().getScreenSize().height;// 获取屏幕的高度
this.setLocation((width - 500) / 2, (height - 500) / 2); // 设置窗体的位置（居中）
this.setResizable(false); // 设置窗体不可以放大
// this.setLocationRelativeTo(null);//这句话也可以设置窗体居中
/*
* 菜单栏的目录设置
*/
// 设置菜单栏
JMenuBar bar = new JMenuBar();
this.setJMenuBar(bar);
// 添加菜单栏目录
JMenu menu1 = new JMenu("游戏菜单"); // 实例化菜单栏目录
JMenu menu2 = new JMenu("设置");
JMenu menu3 = new JMenu("帮助");
bar.add(menu1); // 将目录添加到菜单栏
bar.add(menu2);
bar.add(menu3);

JMenu menu4 = new JMenu("博弈模式"); // 将“模式”菜单添加到“设置”里面
menu2.add(menu4);

// JMenuItem item1=new JMenuItem("人人博弈");
// JMenuItem item2=new JMenuItem("人机博弈");
// 设置“”目录下面的子目录
JRadioButtonMenuItem item1 = new JRadioButtonMenuItem("人人博弈");
JRadioButtonMenuItem item2 = new JRadioButtonMenuItem("人机博弈");
// item1按钮添加时间并且为匿名类
item1.addMouseListener(new MouseListener() {

3.最后设置整个游戏的入口主函数StartEntrance.java

package StartGame;

import javax.swing.JFrame;

public class StartEntrance {
//public static boolean canPlay =false;
public static void main(String[] args) {
// 实例化一个窗口

MyFrame myFrame = new MyFrame();
myFrame.setVisible(true); // 设置窗口为可见
myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // 设置窗口关闭操作属性

}

}

以上所有代码均调试通过，人机算法较为简单，可实现简单的防守功能。
