1、迷你DVD管理器java实 验 报 告 课程名称：面向对象信息系统开发 实 验：期中大作业 班 级：02 学生姓名：李康 序 号：34 学 号：20231060261 专 业：电子信息工程 指导教师：高莲 学 期：2023-2023学年春季学期 成 绩： 云南大学信息学院 请用Java编程语言编写一个迷你DVD管理器，实现功能具体如下：x新增DVD x查看DVD x删除DVD x借出DVD x归还DVD 说明: 1、DVD相关信息如下：DVD的名称、是否可以借出，借出时间，租金每天多少钱、借出次数。 2、程序开始时，对数组进行初给化：3、编写采单，实现功能选择，用控制语句实现: 4、DVD借出
2、后请计算租金：5、根据每张碟的借出次数对DVD进行排序并输出。 源代码： 1. package dvd; import java.util.Scanner; /xx x x author d x/ public class DVD implements add,back,delete,lend,look Scanner input = new Scanner(System.in); private String name; private String yesorno; private int money; private int days; private int times; privat
3、e int nowdays; private String result; DVD() DVD(String name,String yesorno,int money,int days,int times,int nowdays,String result) this.name=name; this.yesorno=yesorno; this.money=money; this.days=days; this.times=times; this.nowdays=nowdays; this.result=result; public void getadd() System.out.print
4、(“请输入该DVD名称：“); this.name = input.nextLine(); System.out.print(“请输入是否可以租赁：“yesor“no)“); this.yesorno = input.nextLine(); if(“yes“.equals(this.yesorno) System.out.print(“请输入租赁一天的费用元：“); this.money = input.nextInt(); this.days =0; this.result=“no“; this.times =0; public void getback() if(“yes“.equals(
5、this.result) System.out.println(“归还成功“); this.result=“no“; else System.out.println(“您未租赁该设备“); public void getdelete() this.name=null; this.yesorno=null; this.money=0; this.days=0; this.times=0; System.out.print(“删除成功“); public void getlend() if(“yes“.equals(this.yesorno)&“no“.equals(this.result)/no
6、未借出 System.out.print(“请输入借用时间“); this.nowdays = input.nextInt(); System.out.println(“需要费用“+this.nowdaysxthis.money+“元“); this.result=“yes“; this.days=this.days+this.nowdays; this.times+; else System.out.println(“该DVD不允许借出或已经借出“); public int copy() return this.times; public void getlook() System.out.
7、println(“该DVD的名称为“+this.name); if(! “yes“.equals(this.yesorno) System.out.println(“该DVD不能借出“); else System.out.println(“该DVD能借出“); System.out.println(“该DVD借出一天需要“+this.money+“元“); System.out.println(“该DVD的总借出时间为“+this.days+“天“); System.out.println(“该DVD的借出次数为“+this.times+“次“); Override public void a
