java练习图书借阅管理系统

好的，下面是一个简单的Java图书借阅管理系统的代码示例，仅供参考：

import java.util.ArrayList;
import java.util.Scanner;

public class BookManagementSystem {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        ArrayList<Book> books = new ArrayList<Book>();
        int choice = 0;
        
        while (choice != 5) {
            System.out.println("1. Add a book");
            System.out.println("2. Search a book");
            System.out.println("3. Display all books");
            System.out.println("4. Remove a book");
            System.out.println("5. Exit");
            System.out.print("Enter your choice: ");
            choice = input.nextInt();
            
            switch (choice) {

                    break;
                default:

}

这个简单的图书借阅管理系统允许你添加图书、搜索图书、显示所有图书和删除图书。你可以根据自己的需求对代码进行修改和扩展。
