找出所有点: 根据斜率按照一个方向递增,求出对应的另一个方向的整数值. Point pStart = new Point(0, 2); Point pEnd = new Point(8, 2); //定义线上的点 List<Point> linePoint = new List<Point>(); //定义x坐标的大小 Point pointMaxX = new Point(); Point pointMinX = new Point(); //给x坐标大的点和小的点赋值 if (

最近用到了根据经纬度计算地球表面两点间距离的公式,然后就用JS实现了一下. 计算地球表面两点间的距离大概有两种办法. 第一种是默认地球是一个光滑的球面,然后计算任意两点间的距离,这个距离叫做大圆距离(The Great Circle Distance). 公式如下: 使用JS来实现为: var EARTH_RADIUS = 6378137.0; //单位M var PI = Math.PI; function getRad(d){ re
问题:输入一个整数,计算它各位上数字的和 Scanner sc = new Scanner(System.in); int a = sc.nextInt(); int sum = 0; while(a!=0){ sum = sum+a%10; a=(int)a/10; } System.out.println(sum);
