java表格实现管理员对书籍的操作

好的，我可以帮你完成这个任务。假设你已经使用Java中的GUI库（如Swing或JavaFX）创建了一个表格用于存储书籍信息，你需要创建一个管理员界面，允许管理员对书籍进行操作。

下面是一个简单的示例代码，演示如何使用Swing创建一个管理员界面，允许管理员添加、编辑和删除书籍：

import javax.swing.*;
import javax.swing.table.DefaultTableModel;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;

public class AdminGUI extends JFrame implements ActionListener {

    private JTable table;
    private DefaultTableModel model;
    private ArrayList<Book> books;

    public AdminGUI() {
        setTitle("Admin Panel");
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setSize(500, 500);
        setLayout(new BorderLayout());

        // Create table model
        String[] columns = {"ID", "Title", "Author", "Publication Date"};
        model = new DefaultTableModel(columns, 0);

        // Create table and set model
        table = new JTable(model);
        add(new JScrollPane(table), BorderLayout.CENTER);

        // Create buttons for adding, editing, and deleting books
        JButton addButton = new JButton("Add Book");
        addButton.addActionListener(this);
        JButton editButton = new JButton("Edit Book");
        editButton.addActionListener(this);
        JButton deleteButton = new JButton("Delete Book");
        deleteButton.addActionListener(this);

        // Add buttons to panel
        JPanel buttonPanel = new JPanel(new FlowLayout());
        buttonPanel.add(addButton);
        buttonPanel.add(editButton);
        buttonPanel.add(deleteButton);

        // Add panel to frame
        add(buttonPanel, BorderLayout.SOUTH);

        // Initialize book list
        books = new ArrayList<>();

        setVisible(true);
    }

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

    @Override
    public void actionPerformed(ActionEvent e) {
        if (e.getActionCommand().equals("Add Book")) {
            // Create dialog for entering book information
            JTextField idField = new JTextField();
            JTextField titleField = new JTextField();
            JTextField authorField = new JTextField();
            JTextField dateField = new JTextField();
            Object[] message = {
                    "ID:", idField,
                    "Title:", titleField,
                    "Author:", authorField,
                    "Publication Date:", dateField
            };
            int option = JOptionPane.showConfirmDialog(this, message, "Add Book", JOptionPane.OK_CANCEL_OPTION);

            // Add book to table if OK is clicked
            if (option == JOptionPane.OK_OPTION) {
                int id = Integer.parseInt(idField.getText());
                String title = titleField.getText();
                String author = authorField.getText();
                String date = dateField.getText();
                Book book = new Book(id, title, author, date);
                books.add(book);
                String[] row = {Integer.toString(id), title, author, date};
                model.addRow(row);
            }
        } else if (e.getActionCommand().equals("Edit Book")) {
            // Edit selected book in table
            int selectedRow = table.getSelectedRow();
            if (selectedRow != -1) {
                int id = Integer.parseInt(model.getValueAt(selectedRow, 0).toString());
                String title = model.getValueAt(selectedRow, 1).toString();
                String author = model.getValueAt(selectedRow, 2).toString();
                String date = model.getValueAt(selectedRow, 3).toString();
                JTextField idField = new JTextField(Integer.toString(id));
                JTextField titleField = new JTextField(title);
                JTextField authorField = new JTextField(author);
                JTextField dateField = new JTextField(date);
                Object[] message = {
                        "ID:", idField,
                        "Title:", titleField,
                        "Author:", authorField,
                        "Publication Date:", dateField
                };
                int option = JOptionPane.showConfirmDialog(this, message, "Edit Book", JOptionPane.OK_CANCEL_OPTION);
                if (option == JOptionPane.OK_OPTION) {
                    int newId = Integer.parseInt(idField.getText());
                    String newTitle = titleField.getText();
                    String newAuthor = authorField.getText();
                    String newDate = dateField.getText();
                    Book newBook = new Book(newId, newTitle, newAuthor, newDate);
                    books.set(selectedRow, newBook);
                    model.setValueAt(newId, selectedRow, 0);
                    model.setValueAt(newTitle, selectedRow, 1);
                    model.setValueAt(newAuthor, selectedRow, 2);
                    model.setValueAt(newDate, selectedRow, 3);
                }
            }
        } else if (e.getActionCommand().equals("Delete Book")) {
            // Delete selected book from table
            int selectedRow = table.getSelectedRow();
            if (selectedRow != -1) {
                books.remove(selectedRow);
                model.removeRow(selectedRow);
            }
        }
    }

    private class Book {
        private int id;
        private String title;
        private String author;
        private String date;

        public Book(int id, String title, String author, String date) {
            this.id = id;
            this.title = title;
            this.author = author;
            this.date = date;
        }
    }
}

这段代码创建了一个管理员界面，允许管理员添加、编辑和删除书籍。当管理员点击“Add Book”按钮时，程序会弹出一个对话框，让管理员输入书籍信息，并将这些信息添加到表格中。当管理员选择一行并点击“Edit Book”按钮时，程序会弹出一个对话框，允许管理员编辑该书籍的信息。当管理员选择一行并点击“Delete Book”按钮时，程序会从表格中删除该书籍的信息。你可以根据自己的需求来修改这段代码。
