Perhaps you have multiple input sources, and they all use different header names or positions for the same data. With profiles, you don't have to create different beans with the same fields and different annotations for each input. Simply annotate the same field multiple times and specify the profile when you parse the input.
The same applies to output: if you want to be able to represent the same data in multiple CSV formats (that is, with different headers or orders), annotate the bean fields multiple times with different profiles and specify which profile you want to use on writing.
Results are undefined if profile names are not unique.
If the same configuration applies to multiple profiles, simply list all applicable profile names here. This parameter is an array of strings.
The empty string, which is the default value, specifies the default profile and will be used if no annotation for the specific profile being used can be found, or if no profile is specified.
