public void write(int b) throws java.io.IOException
write
is that one byte is written
to the output stream. The byte to be written is the eight
low-order bits of the argument b
. The 24
high-order bits of b
are ignored.
Subclasses of OutputStream
must provide an
implementation for this method.
write
in class java.io.OutputStream
b
- the byte
.
java.io.IOException
- if an I/O error occurs. In particular,
an IOException
may be thrown if the
output stream has been closed.public void write(byte[] b, int off, int len) throws java.io.IOException
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.
write
in class java.io.OutputStream
b
- the data.off
- the start offset in the data.len
- the number of bytes to write.
java.io.IOException
- if an I/O error occurs. In particular,
an IOException
is thrown if the output
stream is closed.public void close() throws java.io.IOException
close
is that it closes the output stream. A closed stream cannot perform
output operations and cannot be reopened.
The close
method of OutputStream
does nothing.

in interface java.io.Closeable
close
in class java.io.OutputStream
java.io.IOException
- if an I/O error occurs.
