编写程序实现简单的三子棋游戏。在三子棋中双方在3×3的棋盘中轮流下棋一方用*示另一方用O表示。如果一方的3个棋子占据了同一行同一列或者对角线则该方获胜。如果棋盘已被棋子占满但没有一方获胜则出现平局。在程序中一方为用户用户在界面上输入每次下棋的位置另一方下棋的位置为随机自动生成。

8-3绘制随机图形
定义4个类MyShape、MyLine、MyRectangle和MyOval其中MyShape是其他三个类的父类。MyShape为抽象类包括图形位置的四个坐标一个无参的构造方法将所有的坐标设置为0一个带参的构造函数将所有的坐标设置为相应值每个坐标的设置和读取方法abstract void draw(Graphics g)方法。MyLine类负责画直线实现父类的draw方法MyRectangle负责画矩形实现父类的draw方法MyOval负责画椭圆实现父类的draw方法。编写一个应用程序使用上面定义的类随机选取位置和形状绘制20个图形。

}8-4猜数游戏
编写一个猜数程序该程序随机在1到1000的范围中选择一个供用户猜测的整数。界面上提供一个文本框来接收用户输入的猜测的数如果用户猜得太大则背景变为红色如果猜得太小背景变为蓝色。用户猜对后文本框变为不可编辑同时提示用户猜对了。界面上提供一个按钮使用户可以重新开始这个游戏。在界面上还需显示用户猜测的次数。 实验步骤 (1) 定义继承自JFrame的类在该类中添加界面各部分 (2) 定义事件监听器类完成事件处理 (3) 定义一个包含main方法的测试类在该类中创建框架类对象并显示。 实验提示 (1) 使用面板进行页面布局 (2) 可以使用内部类定义事件监听器类 (3) 按钮点击通过处理ActionEvent事件来完成响应。
