1、__________________________________________________开始输入数据数量number，数据array[]，以及相应的数据名称Array[]i=0；总数SUM=0；i

2、________________________________________________________________________________2、程序代码importjava.applet.*;importjava.awt.*;publicclassGraphextendsApplet{publicvoidpaint(Graphicsg){finalintarray[]={50,130,170,300,250,100};finalStringArray[]={"婴儿","儿童","少年","青年","中年"

3、,"老年"};finalintnumber=6;intStartAngle=0,ArcAngle=0;finalintHIGH=450;inthigh=0,COLOR=0,wi=60;doubleroto=0;StringRoto="0";intSUM=0;for(inti=0;i

4、Fontf=newFont("黑体",Font.TRUETYPE_FONT,20);g.setFont(f);g.drawString("图例:",50,HIGH+50);g.drawOval(600,200,HIGH,HIGH);//画圆for(inti=0;i

5、ouble(high*3.6/10);ArcAngle=D1.intValue();COLOR=i*30;//颜色Colorc=newColor(10,225-COLOR,COLOR);g.setColor(c);if(i>0)wi=wi+35;g.fillRect(wi,(HIGH-high),25,high);//画直方图if(i==number-1)g.fillArc(600,200,HIGH,HIGH,StartAngle,360-StartAngle);_______________________________

6、_____________________________________________________________________elseg.fillArc(600,200,HIGH,HIGH,StartAngle,ArcAngle);//饼图g.fillRect(50,HIGH+55+25*i,20,20);//以下为图例g.drawString(Array[i]+""+Roto+"%",100,HIGH+75+25*i);}//theendoffor(1)//}//theendofif}//theendofpai

7、nt}//theendofTest2、运行结果输入的数据婴儿50，儿童130，少年170，青年300，中年250，老年100__________________________________________________
