如何从sql查询中获取结果后提取字符串和println

import java.sql.*;

public class Main {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/mydatabase";
        String username = "root";
        String password = "password";

        try (Connection connection = DriverManager.getConnection(url, username, password)) {
            String sql = "SELECT column_name FROM table_name WHERE condition";
            Statement statement = connection.createStatement();
            ResultSet resultSet = statement.executeQuery(sql);

            // 提取字符串并打印输出
            while (resultSet.next()) {
                String result = resultSet.getString("column_name");
                System.out.println(result);
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
