编写一个线段类 MyLine，要求如下: 主要属性有： x ，y ；类型为Point (查看API) 编写构造方法，如 MyLine(Point p1 , Point p2) 编写5个成员方法。如： 检查线段是否位于第一象限check()… 求线段的长度 length() … 判断两条直线是否相交(另一线段作为参数)。 编写一点到该线段（或延长线）的距离 其他方法。 注：编写方法时，考虑利用Point类的方法 编写测试程序-Write a segment class MyLine, requirements are as follows: The main attributes are: x, y type Point (see API) the preparation of construction methods, such as MyLine (Point p1, Point p2) prepared by five members of the method. Such as: Check whether the line segment in the first quadrant check () ... order to segment the length of the length () ... to determine whether the two straight lines intersect (the other segment as a parameter). The preparation of 1:00 to the line segment (or extension) of the distance from other methods. Note: The preparation method, consider using the Point class approach to preparing test program
