Description: java写的围棋游戏小程序
开发思路
调用applet类作为父类。在init事件中调用Qipan类，作出panel，上加控制用控件。在paint事件里调用drawline函数画棋盘，注册鼠标动作。鼠标单击位置上用drawoval画出棋子，
事件处理过程
A。重新开始
B。选择尺寸
C。悔棋事件
D。前进事件
有三个文件Weiqi.java，Qizi.java，Qipan.java

Description: java中大部分对图形、文本、图像的操作方法都定义在Graphics类中，所以此次实验使用的方法如Color(int r, int g,int b), setColor(Color c),drawline(int x1,int y1,int x2,int y2)等都来自Graphics类中，此外对文本和字体的处理还用到了Font类中的 new Font(“字体名”，字体风格，字体大小)，setFont（Font f）等方法；-Most of java on the graphics, text, images, methods of operation defined in the Graphics class, so the experimental methods such as the use of Color (int r, int g, int b), setColor (Color c), drawline (int x1 , int y1, int x2, int y2) are from the Graphics class, in addition to text and font handling is also used in the Font class of new Font ( Font name , font style, font size), setFont (Font f) and other methods
