例 9.4对象数组

public class cjava {
    public static void main(String[] args) {
       Box a[]= {new Box(10,12,15),new Box(15,18,20),new Box(16,20,26)};
       System.out.println("The volume of a[0] is "+a[0].volume());
       System.out.println("The volume of a[1] is "+a[1].volume());
       System.out.println("The volume of a[2] is "+a[2].volume());
}
}
class Box{
    int height;
    int width;
    int length;
    Box(int h,int w,int len){
        height=h;
        width=w;
        length=len;
    }
    int volume() {
       return (height*width*length);
    }
}
