名称 'flight_Num' 必须匹配模式 '^[az][a-zA-Z0-9]*$'
means that the _ character in flight_Num is not allowed.
表示不允许使用 flight_Num 中的 _ 字符。

You may want to look at the checkstyle documentation, and I expect you will see this when you fix the first problem, but remove the underscore from the parameter names.
您可能想查看 checkstyle 文档，我希望您在解决第一个问题时会看到这一点，但从参数名称中删除下划线。
NonRefundable(String flightNum, Itinerary tripData, double baseFare,
double fareAdjustmentFactor, double discountFactor)

You can look at various style guides and the parameter name tends to be camel-cased, as shown in this particular one.
您可以查看各种样式指南，参数名称往往是驼峰式的，如这个特定的指南所示。

If it is not possible to remove the underscore it is possible to suppress this with:
如果无法删除下划线，则可以使用以下方法来抑制它：
// SUPPRESS CHECKSTYLE ParameterName
NonRefundable(...)
