如何将JDBC查询的结果保存到变量中？

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class JdbcExample {
    public static void main(String[] args) {
        String url = "jdbc:mysql://localhost:3306/your_database_name";
        String username = "your_username";
        String password = "your_password";

        try {
            // 加载并注册JDBC驱动程序
            Class.forName("com.mysql.jdbc.Driver");

            // 建立数据库连接
            Connection connection = DriverManager.getConnection(url, username, password);

            // 创建Statement对象
            Statement statement = connection.createStatement();

            // 执行SQL查询
            ResultSet resultSet = statement.executeQuery("SELECT * FROM your_table_name");

            // 遍历ResultSet对象并将结果保存到变量中
            while (resultSet.next()) {
                int id = resultSet.getInt("id");
                String name = resultSet.getString("name");
                System.out.println("ID: " + id + ", Name: " + name);
            }

            // 关闭资源
            resultSet.close();
            statement.close();
            connection.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
