3.4 Creating a Custom Shape

You can implement the Shape interface to create a class that defines a new type of shape. It doesn't matter how you represent the shape internally, as long as you can implement the Shape interface methods. The Shape mu st be able to generate a path that specifies its contour.

For example, you could create a simple implementation of Shape that represents polygons as arrays of points. Once the polygon is built, it could be passed to draw, setClip, or any other method that expects a Shape object as an argument.

The PolygonPath class must implement the Shape interface methods:

• contains
• getBounds
• getBounds2D
• getPathIterator
• intersects
