This section illustrates you how to draw different curves with the class
The QuadCurve2D class provides a quadratic parametric curve segments. We are providing you an
example which shows different curves.
In the given example, we have used Vector class to implement an array of
objects. The components of this class can be accessed using an index. The
method vector.size() of Vector class returns the number of
components in the vector. The method vector.elementAt(k)
returns the component at the specified index, in this example we have used 'k'
