The following link gives you both the API page and the .class file for a Point class. Click here for the API for a Point class representing a 2-dimensional point. YOU ARE NOT TO WRITE A Point CLASS, nor any of the methods included in the Point class. The purpose of this lab is to USE the Point class in a program. then used to flex (i.e, illustrate) the methods of the class. The format of the points.text file is: x1 y 1 x y 2 i.e., pairs of x/y coordinates, resulting in data for 2 Point objects per line. The name of your class should be PointApp. For example, if the file points.text contains: 001111111111111111111122 the program should produce the following output: p1 and p2 are equidistant from the origin The distance between (1,1) and (1,1) is 2.0 p1: (1, 1) (quadrant 1) / p2: (1,1) (quadrant 3) p1+p2:(0,0) (quadrant ) p1 and p2 are reflections through the origin p1 and p2 are equidistant from the origin The distance between (1,1) and (1,1) is 2.8284271247461903 p1:(0,0) (quadrant )/p2:(,0) (quadrant ) p1+p2:(0,0) (quadrant 0 ) p1 and p2 are reflections across the x-axis p1 and p2 are reflections across the y-axis p1 and p2 are reflections through the origin p1 and p2 are equidistant from the origin The distance between (,) and (,) is . p1: (1, 1) (quadrant 1) / p2: (1, 1) (quadrant 1) p1+p2: (2,2) (quadrant 1) p1 and p2 are equidistant from the origin The distance between (1,1) and (1,1) is 0.0 p1: (1, 1) (quadrant 1) / p2: (2,2) (quadrant 3) p1+p2:(1,1) (quadrant 3) The distance between (1,1) and (2,2) is 4.242640687119285 The distance between (1,1) and (1,1) is 2.8284271247461903 p1: (0,0) (quadrant 0)/p2:(0,0) (quadrant 0) p1+p2: (0,0) (quadrant 0) p1 and p2 are reflections across the x-axis p1 and p2 are reflections across the y-axis p1 and p2 are reflections through the origin p1 and p2 are equidistant from the origin The distance between (0, 0) and (0,0) is 0.0 p1: (1, 1) (quadrant 1)/p2:(1,1) (quadrant 1) p1+p2: (2, 2) (quadrant 1) p1 and p2 are equidistant from the origin The distance between (1, 1) and (1, 1) is 0.0 p1: (1, 1) (quadrant 1)/p2:(2,2) (quadrant 3) p1+p2: (-1, -1) (quadrant 3 ) The distance between (1, 1) and (-2, -2) is 4.242640687119285 In this exercise, you will be working with a class that represents two-dimensional points (i.e., points with x and y coordinates).
