The basic figure of a square is shown below. Rectangle bounds = new Rectangle(0, 0, -1, -1) įor (int i = 0 i < points. A square is a closed two-dimensional shape with four sides.All four sides of a square are equal and parallel to each other. Negative width and height or it should use the first point in the set Therefore initially construct the Rectangle with a specifically Will contribute that location to the union and add operations.Ĭode attempting to accumulate the bounds of a set of points should That Rectangle will still have a location of (0,0) and Like 2D shapes, a corner is also referred to as a vertex. A corner is created when two or more edges meet. The boundary between two of its surfaces is known as the edge. A three-dimensional shape’s face is a flat surface. Note that a Rectangle constructed with the default no-argumentĬonstructor will have dimensions of 0x0 and therefore be empty. Faces, edges, and corners are a few of these attributes. Operate on its location regardless of whether or not it has a negative Methods which affect only the location of a Rectangle will If two Rectangle objects are combined and each has a negativeĭimension, the result will have at least one negative dimension. Will ignore the Rectangle entirely in generating the result. One of such questions answered is the shape of the object. Point or rectangle will always return false. When you look at an object, some questions come to mind and right there you give quick answers to a number of them. Such a Rectangle is also empty with respect to containmentĬalculations and methods which test if it contains or intersects a Such a Rectangle is treated as non-existant along those axes. Location nor dimension along those axes with negative dimensions. Result as if the add(Point) method were being called.Ī Rectangle whose width or height is negative has neither Will include the location of the Rectangle on that axis in the Methods which combine such a Rectangle with a point or rectangle So, next time when you eat a chocolate bar, get yourself reminded of the definition and properties of a rectangle. Methods which test if an empty Rectangle contains or intersectsĪ point or rectangle will always return false if either dimension is zero. A bar of chocolate is rectangular in shape. The isEmpty() method will return true for such a Rectangle. One, do not prevent setting a negative value for width or height.Ī Rectangle whose width or height is exactly zero has locationĪlong those axes with zero dimension, but is otherwise considered empty. Including the circle, an ellipse is also a non-polygon shape. A polygon which has all the sides and angles as equal is called a regular polygon. Apart from the circle, all the shapes are considered as polygons, which have sides. That create a Rectangle, and the methods that can modify The basic types of 2d shapes are a circle, triangle, square, rectangle, pentagon, quadrilateral, hexagon, octagon, etc. In the coordinate space, its width, and its height. A rectangle is a quadrilateral with four sides and four angles, where all the interior angles are right angles (90 degrees). A Rectangle specifies an area in a coordinate space that isĮnclosed by the Rectangle object's upper-left point
