public Rectangle getBounds()
Rectangle
that completely encloses the Shape
. Note that there is no guarantee that the returned
Rectangle
is the smallest bounding box that encloses the Shape
, only that the Shape
lies entirely within
the indicated Rectangle
. The returned Rectangle
might also fail to completely enclose the Shape
if the
Shape
overflows the limited range of the integer data type. The getBounds2D
method generally returns a tighter
bounding box due to its greater flexibility in representation.getBounds

than that returned by the getBounds

outline. If an optional AffineTransform
is specified, the coordinates returned in the iteration are transformed accordingly.
Each call to this method returns a fresh PathIterator
object that traverses the geometry of the Shape
object
independently from any other PathIterator
objects in use at the same time.
It is recommended, but not guaranteed, that objects implementing the Shape
interface isolate iterations that are in process from
any changes that might occur to the original object's geometry during such iterations.
Before using a particular implementation of the Shape
interface in more than one thread simultaneously, refer to its documentation
to verify that it guarantees that iterations are isolated from modifications.

Shape
outline geometry.
Only SEG_MOVETO, SEG_LINETO, and SEG_CLOSE point types are returned by the iterator.
If an optional AffineTransform
is specified, the coordinates returned in the iteration are transformed accordingly.
The amount of subdivision of the curved segments is controlled by the flatness
parameter, which specifies the maximum distance
that any point on the unflattened transformed curve can deviate from the returned flattened path segments. Note that a limit on the accuracy of
the flattened path might be silently imposed, causing very small flattening parameters to be treated as larger values. This limit, if there is
one, is defined by the particular implementation that is used.
Each call to this method returns a fresh PathIterator
object that traverses the Shape
object geometry independently
from any other PathIterator
objects in use at the same time.
It is recommended, but not guaranteed, that objects implementing the Shape
interface isolate iterations that are in process from
any changes that might occur to the original object's geometry during such iterations.
