Question

Create a class Circle, which

- has a field radius (double)

It should have appropriate accessor and mutator.

 

If the Circle instance is created without parameter, the radius should be set to 1.0. Otherwise the radius should be set to the specified value.

 

The Circle class should have a class level (not instance level) field called Pi. Since Pi is a known constant (3.14159), this field should be a constant. This variable can be accessed directly by outside objects.

 

This Circle class should have a getArea() method and getPerimeter() method. You need to decide their return value and access level.

 

Note:

Area = Pi * radius * radius

Perimeter = 2 * Pi * Radius
