修改实验7中定义的Rectangle类，使之拥有两个构造方法。其中一个是默认的，它使两点的坐标都为（0，0） 另一个带有4个参数，求出左上角和右下角点坐标为（2.1，3.2）、（5.2，6.3）的矩形的周长及面积，再利用带参数的构造方法创建Rectangle对象，求出左上角和右下角点坐标为（1，2）、（6.8，10.5）的矩形的周长及面积.(Modify the definition of experiment 7 Rectangle class, so that it has two constructors. One is the default, it makes two points of the coordinate of (0,0) the other with four parameters, find the upper left and lower right corner coordinates (2.1,3.2), (5.2,6.3) and perimeter and area of ​ ​ a rectangle, and then use a parameterized constructor method to create a Rectangle object, find the upper left and lower right corner coordinates (1,2), (6.8,10.5) rectangle of perimeter and area.)

说明：  1、根据所给的中国版图数据 绘制显示基于北京54坐标系的经纬度数据 编写兰勃特投影转换程序，转换上述数据，并显示 编写墨卡托投影转换程序，转换上述数据，并显示 同时，要绘制相对应的经纬网格，网格间距5度 2、根据所给的世界版图数据 绘制显示基于WGS84坐标系的经纬度数据 编写墨卡托投影转换程序，转换上述数据，并显示 计算北京(116.4，39.8)到巴黎(2.2, 48.52)的大圆轨迹，并显示 同时，要绘制相对应的经纬网格，网格间距5度(1. According to the data of China territory Plot shows latitude and longitude data based on Beijing 54 coordinate system Compile lambert projection conversion program, convert the above data, and display Prepare Mercator projection conversion program, convert the above data, and display At the same time, to draw the corresponding longitude and latitude grid, grid spacing 5 degrees 2. According to the world map data given Draw and display longitude and latitude data based on WGS84 coordinate system Prepare Mercator projection conversion program, convert the above data, and display The great circle trajectory from Beijing (116.4, 39.8) to Paris (2.2, 48.52) is calculated and shown At the same time, to draw the corresponding longitude and latitude grid, grid spacing 5 degrees)
