java简单的图书管理系统（只用java代码不用数据库和可视化界面,一个管理员表和图书表）

java控制台输入图书管理系统信息，（不用数据库和可视化界面，java学习新手秒懂）使用多层框架实现功能

---

图书管理系统需求：
一. 登录页面
1.管理员通过输入用户名和密码能够进入后台进行操作
2.可以进行注册
3.可以退出
二.后台操作有：
1.查询所有图书
2.根据作者查询
3.根据出版社查询图书
4.根据图书名称进行查询
5.增加图书
6.修改图书数量
7.根据图书编号删除图书
8.返回上一菜单
三.类的属性
管理员类 （Admin）
- 序号
- 用户名
- 密码
书库类(Book)
- 图书编号
- 图书名称
- 作者
- 总页数
- 出版社
- 图书数量

案列的项目布局如下图所示：

实体 Admin类的代码

package com.entity;

public class Admin {    
    private int no;   //序号
    private String adid; //用户名
    private String adpwd;//用户密码

    public int getNo() {
        return no;
    }
    public void setNo(int no) {
        this.no = no;
    }
    public String getAdid() {
        return adid;
    }
    public void setAdid(String adid) {
        this.adid = adid;
    }
    public String getAdpwd() {
        return adpwd;
    }
    public void setAdpwd(String adpwd) {
        this.adpwd = adpwd;

    }
    public Admin() {
        super();

}

entity 包下Book类的代码

}

最后就是测试类（Test）的代码

package com.Test;
/**
 * 测试类
 * @author Administrator
 *
 */
public class TestBook {

    public static void main(String[] args) {
        BookMenu menu=new BookMenu();
        menu.showmenu();
    }

}
