题目要求：
构造程序，分别是：
•不能触发Fault。
•触发Fault，但是不能触发Error。
•触发Error，但是不能产生Failure。
问题描述：
假设默认长度单位为米，编写一个计算为各种形状着色花费的程序。
部分代码如下：

9 System.out.println("着色一米的边长需要："+cost.getBorderCost()+"RMB "+"着色l平方米需要:"+cost.getSoliderCost()+"RMB");
10 double radius=0;
11 double height=0,width=0;
12 double left=0,right=0,boom=0;
13 //*******圆*******
14 System.out.print("请输入圆的半径：");
15 radius=input();
16 Circle circle=new Circle(radius);
17 circle.area();
18 circle.perimeter();
19 circle.paintBorder();//为边着色
20 System.out.println("花费为："+cost.calculate(circle));
21
