Class Rectangle

All Implemented Interfaces:
`Shape`, `Serializable`, `Cloneable`
Direct Known Subclasses:
`DefaultCaret`
```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++) {
}```
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++) {
}```

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.

getBounds

`public Rectangle getBounds()`

Gets the bounding `Rectangle` of this `Rectangle`.

This method is included for completeness, to parallel the `getBounds` method of `Component`.

`getBounds` in interface `Shape`
Overrides:
`getBounds` in class `RectangularShape`
Returns:
a new `Rectangle`, equal to the bounding `Rectangle` for this `Rectangle`.
Since:
1.1
`Component.getBounds()`, `setBounds(Rectangle)`, `setBounds(int, int, int, int)`

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 interface `Shape`
Overrides:
`getBounds2D` in class `Rectangle2D`
Returns:
an instance of `Rectangle2D` that is a high-precision bounding box of the `Shape`.

Parameters:
`r` - the specified `Rectangle`
Returns:
`true` if the specified `Rectangle` and this `Rectangle` 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 specified `Rectangle`
Returns:
the largest `Rectangle` contained in both the specified `Rectangle` and in this `Rectangle`; 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 specified `Rectangle`
Returns:
the smallest `Rectangle` containing both the specified `Rectangle` and this `Rectangle`.

```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

`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 new `Point` to add to this `Rectangle`

`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 specified `Rectangle`

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:
`isEmpty` in class `RectangularShape`
Returns:
`true` if the `RectangularShape` 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`.

Specified by:
`outcode` in class `Rectangle2D`
Parameters:
`x` - the specified X coordinate
`y` - the specified Y coordinate
Returns:
the logical OR of all appropriate out codes.
