通过java画一个大风车.doc

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).;/*******@author黄燕斌****@****@since2013-05-28**/lassPoint{privatedoublex;privatedoubley;/***构造器*/publicPoint(){}/***构造器****@paramx****@paramy*/publicPoint(doublex,doubley){=x;=y;}/******@returnX*/publicdoublegetX(){returnx;}/*******@paramxX*/publicvoidsetX(intx){=x;}/*******@returnY*/publicdoublegetY(){returny;}/*******@paramyY*/publicvoidsetY(inty){=y;}}2..;;;/***风车****@author黄****@****@since2013-05-28**/lassWindmill{privatePointcenter;privateintradius;privateColorcolor;publicWindmill(){}/***构造器****@paramcenter****@paramradius****@paramcolor*/publicWindmill(Pointcenter,intradius,Colorcolor){=radius;=center;=color;}etColor(){returncolor;}publicvoidsetColor(Colorcolor){=color;}publicPointgetCenter(){returncenter;}publicvoidsetCenter(Pointcenter){=center;}publicintgetRadius(){returnradius;}publicvoidsetRadius(intradius){=radius;}/***画风车****@paramg*/publicvoiddraw(Graphicsg){/***通过计算出风车10点的位置*/intarrayX[]=newint[10];intarrayY[]=newint[10];Pointp1=newPoint((),()+radius);Pointp3=newPoint(()+(18*)*radius,()+(18*)*radius);Pointp5=newPoint(()+(54*)*radius,()-(54*)*radius);Pointp7=newPoint(()-(54*)*radius,()-(54*)*radius);Pointp9=newPoint(()-(18*)*radius,()+(18*)*radius);doubleT=;Pointp2=newPoint((),()-T*radius);Pointp4=newPoint(()-(18*)*T*radius,()-(18*)*T*radius);Pointp6=newPoint(()-(54*)*T*radius,()+(54*)*T*radius);Pointp8=newPoint(()+(54*)*T*radius,()+(54*M
