Shape entirely contains the

rectangular area must lie within the Shape for the entire
rectanglar area to be considered contained within the
Shape.

intersects(java.awt.geom.Rectangle2D)public java.awt.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.

Shape than the getBounds method. Note that
there is no guarantee that the returned Rectangle2D 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.

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.

object that traverses the Shape object geometry

intersect the Shape if any point is contained in both the
interior of the Shape and the specified rectangular area.
