Hello @GutoVeronezi
Thank you for your PR.
The name `setSelectedFieldNames1 is confusing because it is not symmetric
(for lack of a better word) with `setExcludeFieldNames`, I think it would be
best as `setIncludeFieldNames` which then is a bit odd since ALL fields are
included by default, so there should be _clear_ documentation that using
`setIncludeFieldNames` overrides this default behavior.
The following behavior should throw an `IllegalStateException` IMO:
```
ReflectionToStringBuilder reflectionToStringBuilder = new
ReflectionToStringBuilder(example, ToStringStyle.JSON_STYLE);
reflectionToStringBuilder.setIncludedFieldNames("a", "b", "e");
reflectionToStringBuilder.setExcludedFieldNames("a", "b", "e"); //
throws IllegalStateException?
System.out.println(reflectionToStringBuilder.build()); // throws
IllegalStateException?
```
IOW what does it mean to set a field as both included and excluded, does the
"last API call win" or, does the code simply throw an `IllegalStateException`
if the include and exclude set intersect?
