The following is the mock question in HFSJ.
One of the options "the MyFunctions class may be used by EL even though it has a public constructor." In the
book, this option is correct. The comment say "because EL ignores all instance methods, EL doesn't care that it's dealing with a concrete class"
Three things I don't understand:
1. the option itself (the part after "even though")
2. the comment for this option.
3. Still I don't know if EL can use a constructor
What do you think?
