I see two mistakes:

1. Method ind is defined with return type String, but you attempt to return a char. Which is correct?
2. Variable i is defined in the for loop, so it is not available after it, so expression "return sb.charAt(i)" is illegal. Again, I think you need to reconsider what should be returned. I notice you haven't told us what you are trying to do, what your goal is.
