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.
