ns parameter may be negative, even though the skip method of the Reader superclass
throws an exception in this case. Negative values of ns cause the stream to skip backwards. Negative return
values indicate a skip backwards. It is not possible to skip backwards past the beginning of the string.
If the entire string has been read or skipped, then this method has no effect and always returns 0.skip in class ReaderIOException - If an I/O error occurspublic boolean ready()

a string, there is no actual limit, so this argument must not be negative, but is otherwise ignored.IllegalArgumentException - If readAheadLimit is < 0IOException - If an I/O error occurspublic void reset()
