Java圖書管理程序基于控制臺

1、Java圖書管理程序-基于控制臺import java.io.*;import java.util.*;public class BooksManage public static void main(String args)throws IOException,ArrayIndexOutOfBoundsException, ClassNotFoundException String name,author,press,time; Manager manager1=new Manager(); Scanner input=new Scanner(System.in); int i=10; fo

2、r(;i!=0;) System.out.println(*菜單*); System.out.println( 1.添加書本 2.添加報刊 3.添加視頻 4.查詢信息 5.查看所有資料 0.退出 ); System.out.print(選擇：); i=input.nextInt(); switch(i) case 1:System.out.println(開始添加書本信息！); System.out.print(書名：); name=input.next(); System.out.print(作者姓名：); author=input.next(); System.out.print(出版社：
