如何使用Java获取(检索) mysql数据库数据到数组列表，并使用索引打印

import java.sql.*;
import java.util.ArrayList;

public class RetrieveData {
    public static void main(String[] args) {
        try {
            String url = "jdbc:mysql://localhost:3306/数据库名";
            String username = "用户名";
            String password = "密码";
            Connection connection = DriverManager.getConnection(url, username, password);
            
            Statement statement = connection.createStatement();
            String sql = "SELECT * FROM 表名";
            ResultSet resultSet = statement.executeQuery(sql);
            
            ArrayList<String> dataList = new ArrayList<>();
            while (resultSet.next()) {
                String data = resultSet.getString("列名");
                dataList.add(data);
            }
            
            for (int i = 0; i < dataList.size(); i++) {
                System.out.println("索引 " + i + ": " + dataList.get(i));
            }
            
            resultSet.close();
            statement.close();
            connection.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
