java代码实现图书管理系统

好的，我可以给出一些 Java 代码来实现图书管理系统。首先，我们可以定义一个图书类来表示图书，其中包含图书的标题、作者、出版社、ISBN 等信息。

public class Book {
    private String title;
    private String author;
    private String publisher;
    private String isbn;

    public Book(String title, String author, String publisher, String isbn) {
        this.title = title;
        this.author = author;
        this.publisher = publisher;
        this.isbn = isbn;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public String getPublisher() {
        return publisher;
    }

    public void setPublisher(String publisher) {
        this.publisher = publisher;
    }

    public String getIsbn() {
        return isbn;
    }

    public void setIsbn(String isbn) {
        this.isbn = isbn;
    }
}

然后，我们可以创建一个图书库类来管理图书。这个类可以包含一个 ArrayList 来存储图书，以及一些方法来添加、删除、查询和打印图书信息。

import java.util.ArrayList;
import java.util.List;

public class Library {
    private List<Book> books;

    public Library() {
        this.books = new ArrayList<>();
    }

    public void addBook(Book book) {
        books.add(book);
    }

    public void deleteBook(Book book) {
        books.remove(book);
    }

    public List<Book> searchBookByTitle(String title) {
        List<Book> result = new ArrayList<>();
        for (Book book : books) {
            if (book.getTitle().equals(title)) {
                result.add(book);
            }
        }
        return result;
    }

    public List<Book> searchBookByAuthor(String author) {
        List<Book> result = new ArrayList<>();
        for (Book book : books) {
            if (book.getAuthor().equals(author)) {
                result.add(book);
            }
        }
        return result;
