|
|
* {@code GeneralPath} is a legacy final class which exactly

* Together with {@link Path2D.Double}, the {@link Path2D} classes

* Use {@code Path2D.Float} (or this legacy {@code GeneralPath}
|
|
* subclass) when dealing with data that can be represented
|
|
* and used with floating point precision. Use {@code Path2D.Double}
|
|
* for data that requires the accuracy or range of double precision.
