Hi all,

I have a doubt regarding one of the mock questions in HFSJ(page 432. question 17).

Which abt EL access operators are true?

A. anywhere the . (dot) operator is used, the [] could be used instead.
D. There are some situations where the . (dot) operator must be used and other situations where the [] operator must be used.

In which the answer given is only A. I think the answer D is also correct.
The reason is:
1) We can't use ${musicList.1} instead of ${musicList["1"]
2) we can't use ${initParam.master-email} instead of
${initParam['master-email']}

Can anyone please clarify this?

Thanks and Regards
Swapna

Please search the forum before asking a question. I searched for "EL access operators" and got the following:

https://coderanch.com/t/171338/java-Web-Component-SCWCD/certification/EL-access-operators-HF

which answers your question. Or alternatively:

Thanks for ur reply. I searched in these links. Also, I searched in this forum. They are all discussing only abt option C. But, I couldn't find why the option D is wrong. Can anyone please clarify this.

Thanks

Options A and D are mutually exclusive:

D. There are some situations where the . (dot) operator must be used



This means that there are situations where the "." cannot be replaced with a "[]"

A. anywhere the . (dot) operator is used, the [] could be used instead.



This means that there are no situation where the "." cannot be replaced with a "[]"

Both cannot be rigth at the same time.
