* #### getBounds2D  
public [Rectangle2D](../../../java/awt/geom/Rectangle2D.html "class in java.awt.geom") getBounds2D()  
Returns a high precision and more accurate bounding box of the `Shape` than the `getBounds` method. Note that there is no guarantee that the returned[Rectangle2D](../../../java/awt/geom/Rectangle2D.html "class in java.awt.geom") is the smallest bounding box that encloses the `Shape`, only that the `Shape` lies entirely within the indicated `Rectangle2D`. The bounding box returned by this method is usually tighter than that returned by the `getBounds` method and never fails due to overflow problems since the return value can be an instance of the `Rectangle2D` that uses double precision values to store the dimensions.  
 Note that the [ definition of insideness](../../../java/awt/Shape.html#def%5Finsideness) can lead to situations where points on the defining outline of the `shape` may not be considered contained in the returned `bounds` object, but only in cases where those points are also not considered contained in the original`shape`.  
 If a `point` is inside the `shape` according to the[contains(point)](../../../java/awt/Shape.html#contains-java.awt.geom.Point2D-) method, then it must be inside the returned `Rectangle2D` bounds object according to the [contains(point)](../../../java/awt/Shape.html#contains-java.awt.geom.Point2D-) method of the`bounds`. Specifically:  
`shape.contains(p)` requires `bounds.contains(p)`  
 If a `point` is not inside the `shape`, then it might still be contained in the `bounds` object:  
`bounds.contains(p)` does not imply `shape.contains(p)`  
Specified by:  
`[getBounds2D](../../../java/awt/Shape.html#getBounds2D--)` in interface `[Shape](../../../java/awt/Shape.html "interface in java.awt")`  
Returns:  
an instance of `Rectangle2D` that is a high-precision bounding box of the `Shape`.

1.2
