Hello ,
I found this question and many others exists in the question bank but doesn't exist at standard tests or objective wise tests.

What is the reason for this ?
Should I consider this for me exam preparation ?

You can ignore them. You can go through them only if you have time and interest in learning about those topics.

HTH,

heiii... inner class cannot extend a final class, the answer should be "any non-final" class, not "any class", current "correct" answer is not correct. I know I am munching words but.. that's what it's about, right sorry

The problem statement already says this, "(Provided that the class to be extended is visible and is not final.)".
