Writes
len
bytes from the specified byte array
starting at offset
off
to this output stream.
The general contract for
write(b, off, len)
is that
some of the bytes in the array
b
are written to the
output stream in order; element
b[off]
is the first
byte written and
b[off+len-1]
is the last byte written
by this operation.
The write
method of OutputStream
calls
the write method of one argument on each of the bytes to be
written out. Subclasses are encouraged to override this method and
provide a more efficient implementation.
If b
is null
, a
NullPointerException
is thrown.
If off
is negative, or len
is negative, or
off+len
is greater than the length of the array
b
, then an IndexOutOfBoundsException is thrown.
Parameters:
- b - the data.
- off - the start offset in the data.
- len - the number of bytes to write.
Throws:
- IOException - if an I/O error occurs. In particular,
an IOException
is thrown if the output
stream is closed.
