GradientPaint Example
GradientPaint allows you to fill a shape with a linear gradient between two colors.The first two parameters of the GradientPaint constructor are a start coordinate, and the fourth and fifth parameters an end coordinate. Two color parameters are also provided.
From these a gradient of color is formed. A final parameter tells whether or not the gradient should be cyclic beyond the pairs of coordinates.
GradientPaint can be used in any situation where a Graphics2D graphics context can be obtained, typically from a paint() method.
