关闭多个语句和结果集的有效方法？

Connection connection = null;
Statement statement = null;
ResultSet resultSet = null;

try {
    // 创建连接
    connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");
    
    // 创建语句
    statement = connection.createStatement();
    
    // 执行查询
    resultSet = statement.executeQuery("SELECT * FROM mytable");
    
    // 处理结果集
    while (resultSet.next()) {
        // 处理每一行数据
    }
} catch (SQLException e) {
    // 处理异常
} finally {
    // 关闭结果集
    if (resultSet != null) {
        try {
            resultSet.close();
        } catch (SQLException e) {
            // 处理异常
        }
    }
    
    // 关闭语句
    if (statement != null) {
        try {
            statement.close();
        } catch (SQLException e) {
            // 处理异常
        }
    }
    
    // 关闭连接
    if (connection != null) {
        try {
            connection.close();
        } catch (SQLException e) {
            // 处理异常
        }
    }
}
