Line2D

Line2D is a class commonly found in graphics libraries and programming languages, particularly those dealing with two-dimensional computer graphics. It represents a line segment in a two-dimensional Cartesian coordinate system. A Line2D object typically stores the coordinates of its two endpoints. These endpoints are usually defined by their x and y values. For example, a Line2D might be defined by points (x1, y1) and (x2, y2).

The primary purpose of a Line2D object is to define a straight line path between two points. This allows for various graphical operations. Applications that utilize Line2D include drawing, collision detection, geometric calculations, and vector graphics editing. Libraries often provide methods to manipulate Line2D objects, such as calculating their length, determining if a point lies on the line, or finding the intersection point with another line. The exact implementation and available methods can vary between different graphics frameworks.
