public Rectangle getBounds () [Inherited From RectangularShape]

Returns an integer Rectangle that completely encloses the Shape.

Returns an integer 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.

do not affect any iterations of that geometry that
are already in process.

public boolean intersects (Rectangle2D r) [Inherited From RectangularShape]

Tests if the interior of the Shape intersects the interior of a specified Rectangle2D.

Tests if the interior of the Shape intersects the
interior of a specified Rectangle2D.
The Shape.intersects() method allows a Shape
implementation to conservatively return true when:

there is a high probability that the Rectangle2D and the
Shape intersect, but
the calculations to accurately determine this intersection
are prohibitively expensive.

This means that for some Shapes this method might
return true even though the Rectangle2D does not
intersect the Shape.
The Area class performs
more accurate computations of geometric intersection than most
Shape objects and therefore can be used if a more precise
answer is required.
