<PRE>
public abstract void <B>write</B>(int&nbsp;b)
                    throws <A HREF="../../java/io/IOException.html">IOException</A></PRE>
<DL>
<DD>Writes the specified byte to this output stream. The general 
 contract for <code>write</code> is that one byte is written 
 to the output stream. The byte to be written is the eight 
 low-order bits of the argument <code>b</code>. The 24 
 high-order bits of <code>b</code> are ignored.
 <p>
 Subclasses of <code>OutputStream</code> must provide an 
 implementation for this method.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>b</CODE> - the <code>byte</code>.<DT><B>Throws:</B><DD><CODE><A HREF="../../java/io/IOException.html">IOException</A></CODE> - if an I/O error occurs. In particular, 
             an <code>IOException</code> may be thrown if the 
             output stream has been closed.</DL>

<PRE>
public void <B>write</B>(byte[]&nbsp;b)
           throws <A HREF="../../java/io/IOException.html">IOException</A></PRE>
<DL>
<DD>Writes <code>b.length</code> bytes from the specified byte array 
 to this output stream. The general contract for <code>write(b)</code> 
 is that it should have exactly the same effect as the call 
 <code>write(b, 0, b.length)</code>.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>b</CODE> - the data.<DT><B>Throws:</B><DD><CODE><A HREF="../../java/io/IOException.html">IOException</A></CODE> - if an I/O error occurs.<DT><B>See Also: </B><DD><A HREF="../../java/io/OutputStream.html#write(byte[], int, int)"><CODE>write(byte[], int, int)</CODE></A></DL>

write</H3>
<PRE>
public void <B>write</B>(byte[]&nbsp;b,
                  int&nbsp;off,
                  int&nbsp;len)
           throws <A HREF="../../java/io/IOException.html">IOException</A></PRE>
<DL>
<DD>Writes <code>len</code> bytes from the specified byte array 
 starting at offset <code>off</code> to this output stream. 
 The general contract for <code>write(b, off, len)</code> is that 
 some of the bytes in the array <code>b</code> are written to the 
 output stream in order; element <code>b[off]</code> is the first 
 byte written and <code>b[off+len-1]</code> is the last byte written 
 by this operation.
 <p>
 The <code>write</code> method of <code>OutputStream</code> 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. 
 <p>
 If <code>b</code> is <code>null</code>, a 
 <code>NullPointerException</code> is thrown.
 <p>
 If <code>off</code> is negative, or <code>len</code> is negative, or 
 <code>off+len</code> is greater than the length of the array 
 <code>b</code>, then an <tt>IndexOutOfBoundsException</tt> is thrown.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>b</CODE> - the data.<DD><CODE>off</CODE> - the start offset in the data.<DD><CODE>len</CODE> - the number of bytes to write.<DT><B>Throws:</B><DD><CODE><A HREF="../../java/io/IOException.html">IOException</A></CODE> - if an I/O error occurs. In particular, 
             an <code>IOException</code> is thrown if the output 
             stream is closed.</DL>

<A NAME="flush()"><!-- --></A><H3>
flush</H3>
<PRE>
public void <B>flush</B>()
           throws <A HREF="../../java/io/IOException.html">IOException</A></PRE>
<DL>
<DD>Flushes this output stream and forces any buffered output bytes 
 to be written out. The general contract of <code>flush</code> is 
 that calling it is an indication that, if any bytes previously 
 written have been buffered by the implementation of the output 
 stream, such bytes should immediately be written to their 
 intended destination.
 <p>
 The <code>flush</code> method of <code>OutputStream</code> does nothing.<DD><DL>

<A NAME="close()"><!-- --></A><H3>
close</H3>
<PRE>
public void <B>close</B>()
           throws <A HREF="../../java/io/IOException.html">IOException</A></PRE>
<DL>
<DD>Closes this output stream and releases any system resources 
 associated with this stream. The general contract of <code>close</code> 
 is that it closes the output stream. A closed stream cannot perform 
 output operations and cannot be reopened.
 <p>
 The <code>close</code> method of <code>OutputStream</code> does nothing.<DD><DL>
<DT><B>Throws:</B><DD><CODE><A HREF="../../java/io/IOException.html">IOException</A></CODE> - if an I/O error occurs.</DL>
