-				Returns the [String] at the given [param index] in the array. Returns an empty string and prints an error if the access is out of bounds. Negative indices are not supported; they will always consider the value to be out of bounds and return an empty string.

+				Returns the [String] at the given [param index] in the array. If [param index] is out-of-bounds or negative, this method fails and returns an empty string.
