public int read()
throws IOException
InputStreamint in the range 0 to 255. If no byte is available because
the end of the stream has been reached, the value -1 is returned. This method blocks
until input data is available, the end of the stream is detected, or an exception is thrown.
A subclass must provide an implementation of this method.
read in class InputStream-1 if the end of the stream is reached.IOException - if an I/O error occurs.public int read(byte[] b,
int off,
int len)
throws IOException
InputStreamlen bytes of data from the input stream into an array of bytes. An
attempt is made to read as many as len bytes, but a smaller number may be read. The
number of bytes actually read is returned as an integer.
This method blocks until input data is available, end of file is detected, or an exception is thrown.
If len is zero, then no bytes are read and 0 is returned; otherwise,
there is an attempt to read at least one byte. If no byte is available because the stream is at
end of file, the value -1 is returned; otherwise, at least one byte is read and
stored into b.
The first byte read is stored into element b[off], the next one into
b[off+1], and so on. The number of bytes read is, at most, equal to
len. Let k be the number of bytes actually read; these bytes will be stored
in elements b[off] through b[off+k-1], leaving
elements b[off+k] through b[off+len-1] unaffected.
In every case, elements b[0] through b[off] and elements
b[off+len] through b[b.length-1] are unaffected.
The read(b, off, len) method for class
InputStream simply calls the method read() repeatedly. If the first
such call results in an IOException, that exception is returned from the call to the
read(b, off, len) method. If any subsequent call to
read() results in a IOException, the exception is caught and treated as
if it were end of file; the bytes read up to that point are stored into b and the
number of bytes read before the exception occurred is returned. The default implementation of
this method blocks until the requested amount of input data len has been read, end
of file is detected, or an exception is thrown. Subclasses are encouraged to provide a more
efficient implementation of this method.
