  Tests if the interior of the Shape entirely contains the specified rectangular area.

  Tests if the interior of the Shape entirely contains the specified rectangular area. All coordinates that lie inside the rectangular area must lie within the Shape for the entire rectanglar area to be considered contained within the Shape.

The Shape.contains() method allows a Shape implementation to conservatively return false when:

• the intersect method returns true and
• the calculations to determine whether or not the Shape entirely contains the rectangular area are prohibitively expensive.

This means that for some Shapes this method might return false even though the Shape contains the rectangular area. The Area class performs more accurate geometric computations than most Shape objects and therefore can be used if a more precise answer is required.

  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.

  Tests if the interior of the Shape intersects the interior of a specified rectangular area.

  Tests if the interior of the Shape intersects the interior of a specified rectangular area. The rectangular area is considered to intersect the Shape if any point is contained in both the interior of the Shape and the specified rectangular area.

The Shape.intersects() method allows a Shape implementation to conservatively return true when:

• there is a high probability that the rectangular area 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 rectangular area 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.

rightoff equals leftoff + 4 in order
to avoid allocating extra storage for this common point.
