package BookClass;
public class BookDetail implements Comparable
{
	private String BNum=null;//书号
	private String BName=null;//书名
	private String BWriter=null;//作者
	private float BPrice;//价格
	private String BDescription=null;//书的描述
	private int BStore;//书的存货
	
	//构造函数
	public BookDetail(String BNum,String BName,String BWriter,float BPrice,String BDescription,int BStore)
	{
		this.BNum=BNum;
		this.BName=BName;
		this.BWriter=BWriter;
		this.BPrice=BPrice;
		this.BDescription=BDescription;
		this.BStore=BStore;
	}
	
	//JavaBean函数
	//书号-BNum
	public String getBNum(){
		return this.BNum;
	}
	public void setBNum(String BNun){
		this.BNum=BNum;
	}
	
	//书名-BName
	public String getBName(){

	//compareTo
