（1） 实现一个Point类，该类包含表示坐标的两个int型变量x、y，构造方法Point()和Point(int xx, int yy),返回x值和y值的int getX()和int getY()方法，计算两点间距离的double distance(Point)方法。其中计算平方根用math.sqrt()方法。 （2） 实现一个Circle类，该类包含表示圆心的Point型变量center，表示半径的int radius变量，以及构造方法Circle()、Circle(int xx,int yy,int r)、Circle(Point c,int r)，返回周长和面积的int perimeter()、double area()方法，返回两个圆是否为同一个圆（返回0）、同心圆（返回1）、相交的圆（返回2）、分离的圆（返回3）、包含的圆（返回4）等关系的int relation(Circle c)等方法。PI值可以用math.PI常量。 （3） 实现测试上述两个类的ClassTest类。该类在main方法中分别创建若干个Point对象和Circle对象，并调用相关方法，输出方法的返回值，验证其正确性。 （4） 将Point类、Circle类和主类的包名分别调整为p1、p2、p3，并重新运行，验证是否运行正确。

This sample displays a basic integer calculator powered by the 8051 microcontroller. Although Keil C51 has a full floating point math library the evaluation version is restricted to 2k of object code, so we have constrained this sample to integer maths in order to fit within this limit. The program for this design was written in C using the Keil uVision 2 IDE for which Proteus VSM provides a Debug Monitor driver. Instructions for configuring Proteus to run in conjunction with the Keil environment can be found by editing the 8051 microcontroller on the schematic (point at it and press CTRL-E) and then clicking on the help button on the Edit Component dialogue form.
