【用java在控制台实现简单的图书管理系统】

下面是一个简单的Java控制台应用程序，用于实现图书管理系统的部分功能。这个例子包括添加图书、列出图书列表以及搜索图书。

import java.util.ArrayList;
import java.util.Scanner;
 
public class BookManager {
    private ArrayList<Book> bookList;
 
    public BookManager() {
        bookList = new ArrayList<>();
    }
 
    public void addBook(Book book) {
        bookList.add(book);
        System.out.println("Book added successfully.");
    }
 
    public void listBooks() {
        if (bookList.isEmpty()) {
            System.out.println("No books available.");
            return;
        }
        for (Book book : bookList) {
            System.out.println(book);
        }
    }
 
    public Book searchBook(String title) {
        for (Book book : bookList) {
            if (book.getTitle().equals(title)) {
                return book;
            }
        }
        return null;
    }
 
    public static void main(String[] args) {
        BookManager bookManager = new BookManager();
        Scanner scanner = new Scanner(System.in);
 
        // 添加图书
        System.out.println("Enter book details:");
        System.out.println("Title: ");
        String title = scanner.nextLine();
        System.out.println("Author: ");
        String author = scanner.nextLine();
        Book newBook = new Book(title, author);
        bookManager.addBook(newBook);
 
        // 列出所有图书
        System.out.println("\nList of books:");
        bookManager.listBooks();
 
        // 搜索图书
        System.out.println("\nEnter title to search: ");
        String searchTitle = scanner.nextLine();
        Book foundBook = bookManager.searchBook(searchTitle);
        if (foundBook != null) {
            System.out.println("Found book: " + foundBook);
        } else {
            System.out.println("Book not found.");
        }
 
        scanner.close();
    }
}
 
class Book {
    private String title;
    private String author;
 
    public Book(String title, String author) {
        this.title = title;
        this.author = author;
    }
 
    public String getTitle() {
        return title;
    }
 
    public String getAuthor() {
        return author;
    }
 
    @Override
    public String toString() {
        return "Book{" +
                "title='" + title + '\'' +
                ", author='" + author + '\'' +
                '}';
    }
}

这段代码定义了一个简单的Book类，以及一个BookManager类，它管理着一本书的列表。BookManager有添加图书、列出图书和搜索图书的功能。在main方法中，我们创建了BookManager
