java五子棋人机.doc
介绍：这是一款很简单的人机对战五子棋，只实现了简单的防守功能，适合刚开始设计五子棋的朋友参考。程序执行结果：框架程序：package wuziqi;import java.awt.BorderLayout;import java.awt.Color;import javax.swing.JFrame;/* * 五子棋 */public class MainFrame extends JFrame public static void main(String args) MainPanel panel = new MainPanel();MainFrame frame = new MainFrame("五子棋");frame.setSize(680,680);
