    Default Writing into ViewBuffers!! need help

    I am using a viewbuffer here to copy the string to a file.

    When i copy the string to a byte array and write to a view buffer i get the following error :


    WritingFiles.java:65: cannot find symbol
    symbol : method put(byte[])
    location: class java.nio.CharBuffer
    cbuf.put(bytes);


    public class WritingFiles {
     
        public static void main(String[] args) {
     
     
        File afile = new File("E:/java/samples/testing/proverbs.txt");
     
    String[] sayings = {		" Indecision maximises flexibility ",
        					" Only the mediocre are always at their best "
                              };
     
    FileOutputStream outStream = null;
     
        try
        {
        	outStream = new FileOutputStream (afile,true);
        }catch (FileNotFoundException e)
        {
        	e.printStackTrace(System.err);
        	System.exit(1);
        }
     
        FileChannel outChannel = outStream.getChannel();
     
        int maxlength = 0;
        for ( String saying : sayings )
        	if ( maxlength < saying.length())
         		maxlength = saying.length();
     
        ByteBuffer buf = ByteBuffer.allocate(2*maxlength+4);
     
       try
        {
        	for(String saying : sayings)
        	{
                buf.putInt(saying.length());
                CharBuffer cbuf = buf.asCharBuffer();
                byte[] bytes = saying.getBytes();
                cbuf.put(bytes);
                buf.position(buf.position()+2*saying.length()).flip();
        	    outChannel.write(buf);
        	    buf.clear();
              }
           }
     
        outStream.close();
        	System.out.println("Proverbs written to file");
     
        }catch(IOException e)
        {
        	e.printStackTrace(System.err);
        	System.exit(1);
        }
     
        System.exit(0);
     
        }
    }

    WritingFiles.java:65: cannot find symbol
    symbol : method put(byte[])
    location: class java.nio.CharBuffer
    cbuf.put(bytes);
    See the java doc for CharBuffer. put() doesn't take any byte[] parameter.
