1、今天的作业我做的是画一个风车:运行结果:1首先:写个Point类:（作用作为风车的中点）packagecom.huang.exam;/****@author黄燕斌*@version1.0*@since2013-05-28**/publicclassPoint{privatedoublex;privatedoubley;/***构造器*/publicPoint(){}/***构造器*@paramx*@paramy*/publicPoint(doublex,doubley){this.x=x;this.y=y;}/***@returnX*/publicdoublegetX(){r

2、eturnx;}/****@paramxX*/publicvoidsetX(intx){this.x=x;}/****@returnY*/publicdoublegetY(){returny;}/****@paramyY*/publicvoidsetY(inty){this.y=y;}}2.写一个风车Windmill类packagecom.huang.exam;importjava.awt.Color;importjava.awt.Graphics;/***风车*@author黄*@version1.0*@since2013-05-28**/publicclassWindmi
