如何从ResultSet检索特定记录

import java.sql.*;

public class RetrieveSpecificRecord {
    public static void main(String[] args) {
        Connection connection = null;
        Statement statement = null;
        ResultSet resultSet = null;

        try {
            // 创建数据库连接
            connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");

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

            // 执行查询语句
            resultSet = statement.executeQuery("SELECT * FROM mytable");

            // 遍历结果集
            while (resultSet.next()) {
                // 获取特定列的值
                int id = resultSet.getInt("id");
                String name = resultSet.getString("name");
                // 其他列的获取类似...

                // 处理获取到的值
                System.out.println("ID: " + id);
                System.out.println("Name: " + name);
                // 其他列的处理类似...
            }
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            // 关闭资源
            try {
                if (resultSet != null) {
                    resultSet.close();
                }
                if (statement != null) {
                    statement.close();
                }
                if (connection != null) {
                    connection.close();
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
}
