2016.9.13小程序---继承练习

这里有两件商品都可以去污
肥皂：5元，呈块状
洗衣粉：10元，呈粉末状

根据描述，使用继承方式实现代码。

商品类：

class Goods {
    public String name ;
    public int price ;
    public String state ;
    
    public Goods (String name,int price,String state){
        this.name = name ;
        this.price = price ;
        this.state =state ;
    }
    @Override
    public String toString (){
        return  this.name+" : "+this.price+" 元， "+this.state;
    }
    
}

class soap extends Goods{
    public soap (){
        super ("肥皂",5,"呈块状");
    }
}

class pwoder extends Goods{
    public pwoder (){
        super ("洗衣粉",10,"呈粉末状");
    }
}

测试类：

import javax.swing.JOptionPane;

public class Test  {

    public static void main(String[] args) {
        soap so =new soap();
        pwoder pw = new pwoder();
        System.out.println(so.toString());
        System.out.println(pw.toString());
    }

}
