6,用java做以下题目
import java.awt.Rectangle;public class RectangleHack extends Rectangle //返回周长 public int getPerimeter() return (width + height) * 2; } //返回面积 public int getArea() return width * height; }}创建了一个继承Rectangle的类,然后用这新的类就可以实现返回周长和面积了Dao层
package so.help.dao;
public interface SquareDao // 得到矩形的周长 public Double getPer(Double width,Double height);// 得到矩形的面积 public Double getArea(Double width,Double height);
}
实现层
package so.help.model;
import so.help.dao.SquareDao;
public class Square implements SquareDao public Double getArea(Double width, Double height) return width*height; } public Double getPer(Double width, Double height) return (width+height)*2; }}
这么想若是换成正方形只需要改一下实现层中的方法 public class Rectangle private double chang; private double wide; public double getChang() return chang; } public void setChang(double chang) this.chang = chang; } public double getWide() return wide; } public void setWide(double wide) this.wide = wide; } public double getPerimeter() return 2*(chang+wide); } public double getArea() return chang*wide; } public static void main(String[] args) Rectanglerectangle = new Rectangle(); rectangle.chang=5; rectangle.wide=6; System.out.println("周长为:"+rectangle.getPerimeter()); System.out.println("面积为:"+rectangle.getArea()); } }
