Is "=" considered as an operator? If yes it can take a String object on the right hand side. I marked it in this question and got the question wrong because of that.

= is indeed an operator and so is +=. I see that option 3 is += and is marked as a correct option.

So I am not sure I understand your question. Do you mean you selected this option but were still evaluated as wrong?

HTH,
Paul.

The question was:

Which of the following operators can be used in conjunction with a String object?

And you had to select 3 options.

I chose: +, += and = as answers

The latter was marked wrong stating that '.' (dot) operator is the correct option instead.

But I don't see = as one of the options!

Oops, it looked like equals on my display. Sorry for the mistake.

in the explanation, what does CASE_INSENSITIVE_ORDER mean? And also is it included in the exam?

It is a member of String class. http://docs.oracle.com/javase/6/docs/ap ... TIVE_ORDER

String class is very much a part of the exam objectives so you should at least know about it.

What is this CASE_INSENSITIVE_ORDER for, how can it be used? Can you provide an example?

dot (.) operator accesses members of the String object.

And also methods, right?

members = methods + fields.
