Java图书管理程序基于控制台

1、Java图书管理程序-基于控制台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
