Name 'flight_Num'必须匹配模式' [a-z][a-zA-Z0-9]*$'

I keep getting this error when I run checkstyle on my program:

当我在我的程序上运行checkstyle时，我一直得到这个错误:

    NonRefundable.java:20:28: Name 'flight_Num' must match pattern '^[a-z][a-zA-Z0-9]*$'.

I'm not sure what I need to do to correct this. Here are the comments for this particular error:

     super(flight_Num, trip_Data, base_Fare, fare_AdjustmentFactor);

#1

Name 'flight_Num' must match pattern '^[a-z][a-zA-Z0-9]*$'

Name 'flight_Num'必须匹配模式' [a-z][a-zA-Z0-9]*$'

means that the _ character in flight_Num is not allowed.

表示不允许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.

您可能需要查看checkstyle文档，我希望您在修复第一个问题时将看到这一点，但是要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，参数名称通常是camel- casepe，如图所示。
