1.源程序
package jiekou;
public class jiekou { public static void main (String[] arges)
{ yuanzhui a=new yuanzhui(4,5,6);
yuanzhui b=new yuanzhui(7,8,9);
System.out.println(a.Area());
System.out.println(b.Area());
System.out.println(a.volume());
System.out.println(b.volume());
System.out.println("体积较大的是："+Math.max(a.volume(), b.volume())); }
}
class yuanzhui implements Volume,Area{ protected double r; protected double l;
protected double h;
public yuanzhui(double r,double l,double h){ this.r=r; this.l=l; this.h=h; }
public double volume(){ return Math.PI*Math.pow(r,2)*h/3; }
public double Area(){ return Math.PI*this.r*this.r+this.r*this.l;
}
}
interface Volume{ public double volume(); } interface Area{ public double Area();
}

3.实验心得
程序对我来说太困难了，还需要多多学习。以后还会重新进行调试，多多巩固。多向其他同学请教，把不会的努力掌握。
