Java Character offsetByCodePoints() Method

The offsetByCodePoints(char[]a, int start, int count, int index, int codePointOffset) method of Character class returns the specified index within the given char sub-array which has been offset by codePointOffset codePoints. The start and count parameter specifies a sub-array of the char array. All the unpaired surrogates which lie in the text range given by the index and the codePointOffset are counted as one codePoint each.

Syntax

Parameter

The above method requires five parameters:

  • The char type array.
  • The start which is the index of the first character of the given sub-array.
  • The count is the total length of the sub-array.
  • The index that needs to be offset.
  • The codePointOffset is the offset in the codepoints.

Return Value

The offsetByCodePoints(char[]a, int start, int count, int index, int codePointOffset) method returns the specified index within the subarray.
