This below is the error message.

CodePudding user response:

You must parse the Strings to convert them to the appropriate type, for example to convert a String to a Double, you can use Double.valueOf()

For example:

flight.setDistanceTravelled(Double.valueOf(data[4]));

Other conversions will be more challenging, requiring you to know how dates are formatted in the file.

Often classes has a valueOf() factory method you can use.
