public class Rectangle extends Rectangle2D implements Shape, Serializable
A Rectangle
specifies an area in a coordinate space that is enclosed by the Rectangle
object's upper-left point (x,y)
in the coordinate space, its width, and its height.
A Rectangle
object's width
and height
are public
fields. The constructors that create a Rectangle
, and the methods that can modify one, do not prevent setting a negative value for width or height.
A Rectangle
whose width or height is exactly zero has location along those axes with zero dimension, but is otherwise considered empty. The isEmpty()
method will return true for such a Rectangle
. Methods which test if an empty Rectangle
contains or intersects a point or rectangle will always return false if either dimension is zero. Methods which combine such a Rectangle
with a point or rectangle will include the location of the Rectangle
on that axis in the result as if the add(Point)
method were being called.
Methods which affect only the location of a Rectangle
will operate on its location regardless of whether or not it has a negative or zero dimension along either axis.
Note that a Rectangle
constructed with the default no-argument constructor will have dimensions of 0x0
and therefore be empty. That Rectangle
will still have a location of (0,0)
and will contribute that location to the union and add operations. Code attempting to accumulate the bounds of a set of points should therefore initially construct the Rectangle
with a specifically negative width and height or it should use the first point in the set to construct the Rectangle
. For example:
Rectangle bounds = new Rectangle(0, 0, -1, -1); for (int i = 0; i < points.length; i++) { bounds.add(points[i]); }or if we know that the points array contains at least one point:
Rectangle bounds = new Rectangle(points[0]); for (int i = 1; i < points.length; i++) { bounds.add(points[i]); }
This class uses 32-bit integers to store its location and dimensions. Frequently operations may produce a result that exceeds the range of a 32-bit integer. The methods will calculate their results in a way that avoids any 32-bit overflow for intermediate results and then choose the best representation to store the final results back into the 32-bit fields which hold the location and dimensions. The location of the result will be stored into the x
and y
fields by clipping the true result to the nearest 32-bit value. The values stored into the width
and height
dimension fields will be chosen as the 32-bit values that encompass the largest part of the true result as possible. Generally this means that the dimension will be clipped independently to the range of 32-bit integers except that if the location had to be moved to store it into its pair of 32-bit fields then the dimensions will be adjusted relative to the "best representation" of the location. If the true result had a negative dimension and was therefore non-existent along one or both axes, the stored dimensions will be negative numbers in those axes. If the true result had a location that could be represented within the range of 32-bit integers, but zero dimension along one or both axes, then the stored dimensions will be zero in those axes.

getBounds2D
public Rectangle2D 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
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 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)
method, then it must be inside the returned Rectangle2D
bounds object according to the contains(point)
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
in interfaceShape
- Overrides:
-
getBounds2D

- Returns:
- an instance of
Rectangle2D

intersect;false
otherwise.
intersection
public Rectangle intersection(Rectangle r)
Computes the intersection of this Rectangle
with the specified Rectangle
. Returns a new Rectangle
that represents the intersection of the two rectangles. If the two rectangles do not intersect, the result will be an empty rectangle.
- Parameters:
-
r
- the specifiedRectangle
- Returns:
- the largest
Rectangle
contained in both the specifiedRectangle
and in thisRectangle
; or if the rectangles do not intersect, an empty rectangle.
union
public Rectangle union(Rectangle r)
Computes the union of this Rectangle
with the specified Rectangle
. Returns a new Rectangle
that represents the union of the two rectangles.
If either Rectangle
has any dimension less than zero the rules for non-existent rectangles apply. If only one has a dimension less than zero, then the result will be a copy of the other Rectangle
. If both have dimension less than zero, then the result will have at least one dimension less than zero.
If the resulting Rectangle
would have a dimension too large to be expressed as an int
, the result will have a dimension of Integer.MAX_VALUE
along that dimension.
- Parameters:
-
r
- the specifiedRectangle
- Returns:
- the smallest
Rectangle
containing both the specifiedRectangle
and thisRectangle
.
add
public void add(int newx, int newy)
Adds a point, specified by the integer arguments newx,newy
to the bounds of this Rectangle
.
If this Rectangle
has any dimension less than zero, the rules for non-existent rectangles apply. In that case, the new bounds of this Rectangle
will have a location equal to the specified coordinates and width and height equal to zero.
After adding a point, a call to contains
with the added point as an argument does not necessarily return true
. The contains
method does not return true
for points on the right or bottom edges of a Rectangle
. Therefore, if the added point falls on the right or bottom edge of the enlarged Rectangle
, contains
returns false
for that point. If the specified point must be contained within the new Rectangle
, a 1x1 rectangle should be added instead:
r.add(newx, newy, 1, 1);
- Parameters:
-
newx
- the X coordinate of the new point -
newy
- the Y coordinate of the new point
add
public void add(Point pt)
Adds the specified Point
to the bounds of this Rectangle
.
If this Rectangle
has any dimension less than zero, the rules for non-existent rectangles apply. In that case, the new bounds of this Rectangle
will have a location equal to the coordinates of the specified Point
and width and height equal to zero.
After adding a Point
, a call to contains
with the added Point
as an argument does not necessarily return true
. The contains
method does not return true
for points on the right or bottom edges of a Rectangle
. Therefore if the added Point
falls on the right or bottom edge of the enlarged Rectangle
, contains
returns false
for that Point
. If the specified point must be contained within the new Rectangle
, a 1x1 rectangle should be added instead:
r.add(pt.x, pt.y, 1, 1);
- Parameters:
-
pt
- the newPoint
to add to thisRectangle
add
public void add(Rectangle r)
Adds a Rectangle
to this Rectangle
. The resulting Rectangle
is the union of the two rectangles.
If either Rectangle
has any dimension less than 0, the result will have the dimensions of the other Rectangle
. If both Rectangle
s have at least one dimension less than 0, the result will have at least one dimension less than 0.
If either Rectangle
has one or both dimensions equal to 0, the result along those axes with 0 dimensions will be equivalent to the results obtained by adding the corresponding origin coordinate to the result rectangle along that axis, similar to the operation of the add(Point)
method, but contribute no further dimension beyond that.
If the resulting Rectangle
would have a dimension too large to be expressed as an int
, the result will have a dimension of Integer.MAX_VALUE
along that dimension.
- Parameters:
-
r
- the specifiedRectangle
grow
public void grow(int h, int v)
Resizes the Rectangle
both horizontally and vertically.
This method modifies the Rectangle
so that it is h
units larger on both the left and right side, and v
units larger at both the top and bottom.
The new Rectangle
has (x - h, y - v)
as its upper-left corner, width of (width + 2h)
, and a height of (height + 2v)
.
If negative values are supplied for h
and v
, the size of the Rectangle
decreases accordingly. The grow
method will check for integer overflow and underflow, but does not check whether the resulting values of width
and height
grow from negative to non-negative or shrink from non-negative to negative.
- Parameters:
-
h
- the horizontal expansion -
v
- the vertical expansion
isEmpty
public boolean isEmpty()
Determines whether the RectangularShape
is empty. When the RectangularShape
is empty, it encloses no area.
- Specified by:
-

in classRectangularShape
- Returns:
-
true
if theRectangularShape
is empty;false
otherwise. - Since:
- 1.2
outcode
public int outcode(double x, double y)
Determines where the specified coordinates lie with respect to this Rectangle2D
. This method computes a binary OR of the appropriate mask values indicating, for each side of this Rectangle2D
, whether or not the specified coordinates are on the same side of the edge as the rest of this Rectangle2D
.
