In this assignment, you will find a best fit line to a given 2D point set. Point coordinates -(x, y) pairs- are provided in a text file: coordinates.txt. Each (x, y) point should be stored as a PointXY object. UML diagram for the PointXY class is provided in Figure 1. In the input coordinates file, there are many 2D points. You are required to store all of these points in an Array List, of type PointXY. You are given three coordinate files. Figure 2,3, and 4 show the results of the best fitting line (black line) and input point sets (randomly colored circles, opacity-0.7). As seen in figures, if the points are close to linear, line fits correctly. If the points are non-linear, fitting a line seems inadequate. PointXY +x: int +y: int +PointXY(x: int, y: int) x coordinate value y coordinate value Constructor Figure 1. UML class diagram of the PointXY class. Given a set of n points (x1.y), (x2,Y2), found by , (xn.yn), equation of a best fitting line y ax b can be where- -4:1 y and X =?4:1 X are the means of x and y coordinate values given in the coordinate file. When you run your program with a specified input file, e.g., coordinates1.txt, it should output plots as shown in figures given below. Provide all three output plots in your report. Tip: In order to draw all points within the output window, automatically calculate scene width and height parameters for the Scene constructor using minimum and maximum (x, y) coordinates.
