Area(Shape s)

[Jenny]

Hi,

In Java Doc, it wrote:

Area
public Area(Shape s)The Area class creates an area geometry from the
specified Shape object.

When I looked at Shape, it is an interface. Are there some methods of
some classes that can return a Shape object?

Thanks a lot.

Look at the JavaDoc of Shape. Right at the top it lists "All Known
Implementing Classes". All instances of these classes are Shapes.

Additionally, the "Use" link (top of page, between "Class" and "Tree") lists references to the
class/interface. For Shape:
