	 * 带参构造函数
	 * 
	 * 
	 * @param name

}

商品类：Goods

package entity;

public class Goods {

}

商品标签类：Tag

package entity;

public class Tag {
	private int id = 0;
	//商品一级类目
	private String firstLevel;
	//商品二级类目
	private String secondLevel;

}

商品子类：Book类

package entity;

public class Book extends Goods{
	String author; // 书籍作者	    
	
	
	public Book() {
	}
	public Book(String cid, String name,  int number,float price) {

	}

	}

	public String getAuthor() {
		return author;
	}
	public void setAuthor(String author) {

	}
	
	@Override
	public String toString() {
		return "商品编号：" + this.id + " | 商品名：" + this.name 
				+ " | 商品总数：" + this.number+" |商品价格："+this.price
				+" | 作者：" + this.author+ " | 类目：" + this.tag ;
	}

}

商品子类：Ipad类

package entity;

public class Ipad extends Goods {

	}
	
	public Ipad() {		
	}
