Type Reason Java.Lang.NullPointerException if seq is null. Java.Lang.IndexOutOfBoundsException if index , index >= limit, limit or if limit is greater than the length of seq.
Returns the code point at index in the specified array of character units, where index has to be less than limit. If the unit at index is a high-surrogate unit, index + 1 is less than limit and the unit at index + 1 is a low-surrogate unit, then the supplementary code point represented by the pair is returned; otherwise the char value at index is returned.
