charS in a string

Question

while using the charAt method, can it accept both double and int as an index parameter?

Answer 1

I believe that you would only be able to return an int because it is the CharAt method counts the

number of characters in the index. Therefore, I am unsure how you would be able to have something like charAt(1.5). This is becasue the index is just counting 0123456789....

Hope this helps.
