Question

Have you ever read Hamlet?
- Yes, I have. I have ever read Hamlet.

(Is this short dialogue grammatical? Would you check the last sentence? Is the last sentence right?)

Answer 1

Does the second sentence not seem a bit strange? Does it need the word "ever" ?

Answer 2

I don't think the second sentence is even needed. "Yes, I have" is all you need to answer that question.
