cuboidtest.java

本人在JAVA学习中的一点小实验

class rectangle{
	double length,width;
	public rectangle(double length,double width){
		this.length=length;
		this.width=width;
	}
	public double  area(){
		return length*width;
	}
}
  class cuboid extends rectangle{
  	double height;
  	public cuboid(double l,double w,double h){
  	 super(l,w);
  	    height=h;}
  	   public double volume(){
  	     	return area()*height;
  	     }
  }
  
  
  public class cuboidtest{
  	public static void main(String args[]){
  		cuboid a =new cuboid(10,10,10) ;
  			System.out.println(""+a.area());
  			System.out.println(""+a.volume());
  	}
  }
