Tells whether this stream is ready to be read.
|
void |

throws java.io.IOException
The 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.

mark 在类中 java.io.ReaderreadAheadLimit - Limit on the number of characters that may be
read while still preserving the mark. Because
the stream's input comes from a string, there
is no actual limit, so this argument must not
be negative, but is otherwise ignored.java.lang.IllegalArgumentException - If readAheadLimit < 0java.io.IOException - If an I/O error occurspublic void reset()
