使用Java语言编写一套swing图书管理系统

好的，下面是一个简单的swing图书管理系统的示例代码：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.util.ArrayList;

public class LibrarySystem extends JFrame implements ActionListener {
    private JTextField bookTitleField;
    private JTextField authorField;
    private JTextField isbnField;
    private JTextField publisherField;
    private JTextField yearField;
    private JButton addButton;
    private JButton searchButton;
    private JButton deleteButton;
    private JTextArea resultArea;
    private ArrayList<Book> books;

    public LibrarySystem() {
        super("Library System");

        books = new ArrayList<Book>();

        JPanel inputPanel = new JPanel(new GridLayout(5, 2));
        inputPanel.add(new JLabel("Book Title:"));
        bookTitleField = new JTextField();
        inputPanel.add(bookTitleField);
        inputPanel.add(new JLabel("Author:"));
        authorField = new JTextField();
        inputPanel.add(authorField);
        inputPanel.add(new JLabel("ISBN:"));
        isbnField = new JTextField();
        inputPanel.add(isbnField);
        inputPanel.add(new JLabel("Publisher:"));
        publisherField = new JTextField();
        inputPanel.add(publisherField);
        inputPanel.add(new JLabel("Year:"));
        yearField = new JTextField();
        inputPanel.add(yearField);

        addButton = new JButton("Add");
        addButton.addActionListener(this);
        searchButton = new JButton("Search");
        searchButton.addActionListener(this);
        deleteButton = new JButton("Delete");
        deleteButton.addActionListener(this);

        JPanel buttonPanel = new JPanel(new GridLayout(1, 3));
        buttonPanel.add(addButton);
        buttonPanel.add(searchButton);
        buttonPanel.add(deleteButton);

        resultArea = new JTextArea(10, 40);
        JScrollPane resultScrollPane = new JScrollPane(resultArea);

        setLayout(new BorderLayout());
        add(inputPanel, BorderLayout.NORTH);
        add(buttonPanel, BorderLayout.CENTER);
        add(resultScrollPane, BorderLayout.SOUTH);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(500, 400);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == addButton) {
            String bookTitle = bookTitleField.getText();
            String author = authorField.getText();
            String isbn = isbnField.getText();
            String publisher = publisherField.getText();
            String year = yearField.getText();
            Book book = new Book(bookTitle, author, isbn, publisher, year);
            books.add(book);
            resultArea.setText("Book added: " + book);
        } else if (e.getSource() == searchButton) {
            String searchValue = JOptionPane.showInputDialog(this, "Enter search value:");
            StringBuilder sb = new StringBuilder();
            for (Book book : books) {
                if (book.getTitle().contains(searchValue) || book.getAuthor().contains(searchValue)
                        || book.getIsbn().contains(searchValue) || book.getPublisher().contains(searchValue)
                        || book.getYear().contains(searchValue)) {
                    sb.append(book).append("\n");
                }
            }
            resultArea.setText(sb.toString());
        } else if (e.getSource() == deleteButton) {
            String isbn = JOptionPane.showInputDialog(this, "Enter ISBN of book to delete:");
            boolean deleted = false;
            for (int i = 0; i < books.size(); i++) {
                if (books.get(i).getIsbn().equals(isbn)) {
                    books.remove(i);
                    resultArea.setText("Book with ISBN " + isbn + " deleted.");
                    deleted = true;
                    break;
                }
            }
            if (!deleted) {
                resultArea.setText("Book with ISBN " + isbn + " not found.");
            }
        }
    }

    public static void main(String[] args) {
        new LibrarySystem();
    }
}

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

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

    public String getTitle() {
        return title;
    }

    public String getAuthor() {
        return author;
    }

    public String getIsbn() {
        return isbn;
    }

    public String getPublisher() {
        return publisher;
    }

    public String getYear() {
        return year;
    }

    public String toString() {
        return title + " by " + author + " (" + isbn + "), published by " + publisher + " in " + year;
    }
}

这个系统可以添加、删除和搜索图书，并且将结果显示在一个文本区域中。你可以根据需要进行修改和扩展。

java java编写一个图书管理系统

Java是一种面向对象的编程语言，它可以用于开发各种类型的应用程序，包括图书管理系统。下面是一个简单的Java图书管理系统的实现方式：

1. 首先，需要定义一个Book类，该类包含书籍的基本信息，如书名、作者、出版社、ISBN号等。可以使用以下代码定义Book类：

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 String getAuthor() {
        return author;
    }

    public String getPublisher() {
        return publisher;
    }

    public String getIsbn() {
        return isbn;
    }
}

2. 接下来，需要定义一个BookManager类，该类包含对图书进行管理的方法，如添加图书、删除图书、查找图书等。可以使用以下代码定义BookManager类：

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

public class BookManager {
    private List<Book> books;

    public BookManager() {
        books = new ArrayList<>();
    }

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

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

    public Book findBookByTitle(String title) {
        for (Book book : books) {
            if (book.getTitle().equals(title)) {
                return book;
            }
        }
        return null;
    }

    public Book findBookByAuthor(String author) {
        for (Book book : books) {
            if (book.getAuthor().equals(author)) {
                return book;
            }
        }
        return null;
    }

    public Book findBookByIsbn(String isbn) {
        for (Book book : books) {
            if (book.getIsbn().equals(isbn)) {
                return book;
            }
        }
        return null;
    }
}

3. 最后，可以编写一个简单的控制台程序来测试图书管理系统。可以使用以下代码实现：

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        BookManager manager = new BookManager();
        Scanner scanner = new Scanner(System.in);

        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. 查找图书");
            System.out.println("4. 退出");

            int choice = scanner.nextInt();
            scanner.nextLine();

            switch (choice) {
                case 1:
                    System.out.println("请输入书名：");
                    String title = scanner.nextLine();
                    System.out.println("请输入作者：");
                    String author = scanner.nextLine();
                    System.out.println("请输入出版社：");
                    String publisher = scanner.nextLine();
                    System.out.println("请输入ISBN号：");
                    String isbn = scanner.nextLine();
                    Book book = new Book(title, author, publisher, isbn);
                    manager.addBook(book);
                    System.out.println("添加成功！");
                    break;
                case 2:
                    System.out.println("请输入书名：");
                    title = scanner.nextLine();
                    book = manager.findBookByTitle(title);
                    if (book != null) {
                        manager.removeBook(book);
                        System.out.println("删除成功！");
                    } else {
                        System.out.println("未找到该书！");
                    }
                    break;
                case 3:
                    System.out.println("请选择查找方式：");
                    System.out.println("1. 按书名查找");
                    System.out.println("2. 按作者查找");
                    System.out.println("3. 按ISBN号查找");
                    int searchChoice = scanner.nextInt();
                    scanner.nextLine();
                    switch (searchChoice) {
                        case 1:
                            System.out.println("请输入书名：");
                            title = scanner.nextLine();
                            book = manager.findBookByTitle(title);
                            if (book != null) {
                                System.out.println("书名：" + book.getTitle());
                                System.out.println("作者：" + book.getAuthor());
                                System.out.println("出版社：" + book.getPublisher());
                                System.out.println("ISBN号：" + book.getIsbn());
                            } else {
                                System.out.println("未找到该书！");
                            }
                            break;
                        case 2:
                            System.out.println("请输入作者：");
                            author = scanner.nextLine();
                            book = manager.findBookByAuthor(author);
                            if (book != null) {
                                System.out.println("书名：" + book.getTitle());
                                System.out.println("作者：" +
