      length in interface CharSequence
      Returns:
      the number of chars in this sequence

    • charAt

      public 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.

      subSequence in interface CharSequence
      Parameters:
      start - the start index, inclusive
