在这里插入图片描述

    public static void main(String[] args) {OrientationUse orientationUse = new OrientationUse();orientationUse.test02();}public void test02() {A = new Coordinate(2, 1);B = new Coordinate(2, 2.5);C = new Coordinate(3, 4);int index = Orientation.index(A, B, C);LOGGER.info("index: {}", index);// 17:32:49.033 [main] INFO  pers.stu.algorithm.AngleUse - index: -1}

在这里插入图片描述

    public static void main(String[] args) {OrientationUse orientationUse = new OrientationUse();orientationUse.test00();}public void test00() {A = new Coordinate(2, 1);B = new Coordinate(2, 2.5);C = new Coordinate(2, 4);int index = Orientation.index(A, B, C);LOGGER.info("index: {}", index);// 17:25:11.618 [main] INFO  pers.stu.algorithm.AngleUse - index: 0}

在这里插入图片描述

	public static void main(String[] args) {OrientationUse orientationUse = new OrientationUse();orientationUse.test01();}public void test01() {A = new Coordinate(2, 1);B = new Coordinate(2, 2.5);C = new Coordinate(1, 4);int index = Orientation.index(A, B, C);LOGGER.info("index: {}", index);// 17:32:49.033 [main] INFO  pers.stu.algorithm.AngleUse - index: 1}

在这里插入图片描述
