个人原创代码：编写Java Application程序，定义一个类Point，代表一个点，public属性有x和y，方法有显示点坐标show（），构造函数有两个参数分别给x,y赋值，在main方法中构造两个对象，再创建一方法(getMiddle)为取两个点构成线段的中点的坐标，参数为2个点对象，调用此方法后得到一个新的点，编写Application，显示该对象的坐标值。-Personal original code: using java application program, define a class Point, on behalf of a point, the public attributes x and y, the method of display point coordinates of the show () constructor has two parameters, respectively, to x, y, assignment, in the main methodconstruct two objects, and then create a method (getMiddle,) to display the object is to take two points constitute the coordinates of the midpoint of the segment, the parameters for two points to get a new object, call this method, the preparation of the Application,coordinates.
