So, I went in to a recruiter for a pre-interview, which included a couple of java coding questions. I got the first one right, but found the second one to be rather nonsense--unless I'm just that behind on java syntax.
The question:
Given an object person with a field hair-style (yes, the hyphen is part of it), how do you get the value of hair-style?
I pointed out the syntax error then said that it would have to be either person.hair-style if scope allows or to use an accessor method if one is provided. The recruiter read the correct answer as person[hair-style]. They did show me the text of the question in order to confirm its contents.
I have only worked in Java up to version 8. Is the above some change that was introduced in a later version? I have tried searching online for more information, but am clearly not using the correct search string.
