用java写一个基于控制台的图书管理系统

好的，以下是一个基于控制台的图书管理系统的 Java 代码示例：

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

public class BookManagementSystem {
    private static ArrayList<Book> books = new ArrayList<>();
    private static Scanner scanner = new Scanner(System.in);

    public static void main(String[] args) {
        while (true) {
            System.out.println("请选择操作：");
            System.out.println("1. 添加图书");
            System.out.println("2. 删除图书");
            System.out.println("3. 查看所有图书");
            System.out.println("4. 退出系统");

            int choice = scanner.nextInt();
            switch (choice) {
                case 1:
                    addBook();
                    break;
                case 2:
                    deleteBook();
                    break;
                case 3:
                    showAllBooks();
                    break;
                case 4:
                    System.out.println("感谢使用图书管理系统！");
                    System.exit(0);
                default:
                    System.out.println("无效的选择，请重新输入！");
                    break;
            }
        }
    }

    private static void addBook() {
        System.out.println("请输入图书名称：");
        String name = scanner.next();
        System.out.println("请输入图书作者：");
        String author = scanner.next();
        System.out.println("请输入图书价格：");
        double price = scanner.nextDouble();
        Book book = new Book(name, author, price);
        books.add(book);
        System.out.println("添加成功！");
    }

    private static void deleteBook() {
        System.out.println("请输入要删除的图书名称：");
        String name = scanner.next();
        for (Book book : books) {
            if (book.getName().equals(name)) {
                books.remove(book);
                System.out.println("删除成功！");
                return;
            }
        }
        System.out.println("未找到该图书！");
    }

    private static void showAllBooks() {
        System.out.println("所有图书如下：");
        for (Book book : books) {
            System.out.println(book);
        }
    }
}

class Book {
    private String name;
    private String author;
    private double price;

    public Book(String name, String author, double price) {
        this.name = name;
        this.author = author;
        this.price = price;
    }

    public String getName() {
        return name;
    }

    public String getAuthor() {
        return author;
    }

    public double getPrice() {
        return price;
    }

    @Override
    public String toString() {
        return "Book{" +
                "name='" + name + '\'' +
                ", author='" + author + '\'' +
                ", price=" + price +
                '}';
    }
}

希望这个示例能够帮助你实现一个基于控制台的图书管理系统。
