           throws <A HREF="../../java/io/IOException.html">IOException</A></PRE>
<DL>
<DD>Writes the specified <code>byte</code> to this output stream. 
 <p>
 The <code>write</code> method of <code>FilterOutputStream</code> 
 calls the <code>write</code> method of its underlying output stream, 
 that is, it performs <tt>out.write(b)</tt>.
 <p>
 Implements the abstract <tt>write</tt> method of <tt>OutputStream</tt>.<DD><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 to this output stream. 
 <p>
 The <code>write</code> method of <code>FilterOutputStream</code> 
 calls its <code>write</code> method of three arguments with the 
 arguments <code>b</code>, <code>0</code>, and 
 <code>b.length</code>. 
 <p>
 Note that this method does not call the one-argument 
 <code>write</code> method of its underlying stream with the single 
 argument <code>b</code>.<DD><DL>

<DL>
<DD>Writes <code>len</code> bytes from the specified 
 <code>byte</code> array starting at offset <code>off</code> to 
 this output stream. 
 <p>
 The <code>write</code> method of <code>FilterOutputStream</code> 
 calls the <code>write</code> method of one argument on each 
 <code>byte</code> to output. 
 <p>
 Note that this method does not call the <code>write</code> method 
 of its underlying input stream with the same arguments. Subclasses 
 of <code>FilterOutputStream</code> should provide a more efficient 
 implementation of this method.<DD><DL>

<DL>
<DD>Flushes this output stream and forces any buffered output bytes 
 to be written out to the stream. 
 <p>
 The <code>flush</code> method of <code>FilterOutputStream</code> 
 calls the <code>flush</code> method of its underlying output stream.<DD><DL>

<DL>
<DD>Closes this output stream and releases any system resources

 The <code>close</code> method of <code>FilterOutputStream</code> 
 calls its <code>flush</code> method, and then calls the 
 <code>close</code> method of its underlying output stream.<DD><DL>
