如何使用数据库中的信息将jcombobox单步执行到数组

import java.sql.*;
import javax.swing.*;

public class ComboBoxFromDatabaseExample {
    public static void main(String[] args) {
        // 数据库连接信息
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";

        try {
            // 连接数据库
            Connection connection = DriverManager.getConnection(url, username, password);

            // 查询数据库
            String query = "SELECT option_name FROM options_table";
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery(query);

            // 处理查询结果并存储在数组中
            String[] options = new String[resultSet.getFetchSize()];
            int index = 0;
            while (resultSet.next()) {
                options[index] = resultSet.getString("option_name");
                index++;
            }

            // 创建JComboBox并将数据添加到其中
            JComboBox<String> comboBox = new JComboBox<>(options);

            // 将JComboBox添加到界面
            // ...

            // 关闭数据库连接
            resultSet.close();
            statement.close();
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
