It is a source code using java for showing how to make a hexagon graphic computer simulation

输入n值，打印边长为n的空心正六边形，其边由“*”组成。-Enter the n value, the print side of the hollow regular hexagon for the n, the edge by the " *" component.

在一个正n边形中，所有的边长都相同，且所有的度数都相同。设计一个RegularPolygon的类，要求可以计算这个正多边形的面积和周长。要求画出该类的UML图并实现这个类。编写一个测试程序，分别测试正三角形、正五边形、正六边形的面积和周长。-In an n-gon, all sides are the same length, and all have the same degree. RegularPolygon design a class that requires regular pol
