# Java AWT Rectangle intersection

## Java AWT Rectangle intersection

JavaDoc on intersect method states:

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

While JavaDoc for the whole class specifies:

A Rectangle whose width or height is

negativehas neither location nor

dimension along those axes with negative dimensions. Such a Rectangle

is treated as non-existant along those axes.Such a Rectangle is alsowith respect to containment calculations and methods which test

empty

if it contains or intersects a point or rectangle will always return

false. Methods which combine such a Rectangle with a point or

rectangle will ignore the Rectangle entirely in generating the result.

If two Rectangle objects are combined and each has a negative

dimension, the result will have at least one negative dimension.

So, rectangle created by intersection with both negative dimensions actually means that there is no intersection. You can check this with `intersects()`

method:

```
boolean intersects = rectZR.intersects(rectCorrect);
```
