  charAt

  char charAt (int index)

  Returns the char value at the specified index. An index ranges from zero to length() - 1 . The first char value of the sequence is at index zero, the next at index one, and so on, as for array indexing.

  If the char value specified by the index is a Moved out of a link with destination ../../../java.base/java/lang/Character.html#unicode.Moved to a link with destination Character.html#unicode.surrogate, the surrogate value is returned.

  Parameters:

  index - the index of the char value to be returned

  Returns:

  the specified char value

  Throws:

  IndexOutOfBoundsException - if the index argument is negative or not less than length()

• ✗

  public default java.util.stream.IntStream chars()

  Comparing jdk-20-ga and jdk-21+35

  chars

  default IntStream chars()

  Returns a stream of int zero-extending the char values from this sequence. Any char which maps to a Moved out of a link with destination ../../../java.base/java/lang/Character.html#unicode.Moved to a link with destination Character.html#unicode.surrogate code pointMoved out of a link with destination ../../../java.base/java/lang/Character.html#unicode.Moved to a link with destination Character.html#unicode. is passed through uninterpreted.

  The stream binds to this sequence when the terminal stream operation commences (specifically, for mutable sequences the spliterator for the stream is late-binding ). If the sequence is modified during that operation then the result is undefined.

  Returns:

  an IntStream of char values from this sequence
