I can't understand if assert is always a keyword and it can't be used as identifier,
assert is a keyword, only if compiling with assertion enabled.

I guess assertion enabling and assertion disable (-ea and -da) is only when executing. ie with
command and not javac compiler options.
checking whether assert has been used as a keyword or as a identifier comes into picture when you compile with javac, and when you use the -source options.

I agree. Here's the link:

r they keywords or literals?
