- seq
- the character array to find the index in.
- start
- the inclusive index that marks the beginning of the subsequence.
- count
- the number of char values to include within the subsequence.
- index
- the start index in the subsequence of the char array.
- codePointOffset
- the number of code points to look backwards or forwards; may be a negative or positive value.

Type Reason Java.Lang.NullPointerException if seq is null. Java.Lang.IndexOutOfBoundsException if start , count , index , index > start + count, start + count is greater than the length of seq, or if there are not enough values in seq to skip codePointOffset code points forward or backward (if codePointOffset is negative) from index.
Determines the index in a subsequence of the specified character array that is offset codePointOffset code points from index. The subsequence is delineated by start and count.
