Arc2D

Arc2D is a two-dimensional geometric shape that represents a segment of an ellipse. It is defined by its center point, width, height, start angle, and angular extent. The start angle and angular extent determine the portion of the ellipse that is included in the arc. The arc can be open or closed, depending on whether the angular extent is less than 360 degrees or equal to 360 degrees, respectively. Arc2D is commonly used in computer graphics and geometric modeling to represent curved shapes and paths. It can be created and manipulated using various programming libraries and tools, such as Java's AWT (Abstract Window Toolkit) and Swing frameworks. The Arc2D class in Java provides methods for drawing, filling, and transforming arcs, as well as for determining their properties, such as their bounding box and intersection points with other shapes.
