To produce a program that calculates and outputs the circumference and area of a circle
given its radius.
You are asked to model the system by two classes. An application class Driver containing
the main method, and a class Circle storing the radius of the circle. Such class will have
the responsibility to compute the two required numerical outputs: the length of the
circumference and the area of the circle (as results of methods with the same name).解这道题 小弟在此谢过 很重要的哦

public class Circle
{
public final static double PI=3.14;
private double radius;
private double outputs;
public Circle(double radius)
{
this.radius=radius;
}
public double getCircumference()
{
outputs=2*PI*radius;
return outputs;
}
public double getArea()
{
this.outputs=PI*radius*radius;
return outputs;
}
}
public class Driver
{
public static void main(String args[])
{
Circle c=new Circle(3.0);
System.out.println("The circle's circumference is:"+c.getCircumference());
System.out.println("The circle's area is :"c.getArea());
}
}
太简单了自己动手吧，无非就是写两个类一个圆一个交通工类交通工具类继承圆类，自己动手
