File cannot be opened/corrupted after writing sucessfully using Java NIO file channel

Question

i have the following code which runs without error and writes the output file successfully. However, i am not able to open the output file. it always prompts me an error saying "word found unreadable content"

anyone can advise if there is anything wrong with my code?

`File inputf = new File("C:\\Appl\\CM table deployment.docx");
File outputf = new File("C:\\Appl\\CM table deployment1.docx");

RandomAccessFile infile = new RandomAccessFile(inputf, "r");
RandomAccessFile outfile = new RandomAccessFile(outputf, "rw");
FileChannel inChannel = infile.getChannel();
FileChannel outChannel = outfile.getChannel();


ByteBuffer inbuffer = ByteBuffer.allocate(1024*64);

    long position = 0;

    System.out.println("inChannel.size(): " + inChannel.size());        

    while(inChannel.read(inbuffer) > 0)
              {
                  inbuffer.flip();
                  ByteBuffer outbuffer;

                  if(position+inbuffer.capacity()<inChannel.size())
                         outbuffer = ByteBuffer.allocate(1024*64);

                  else 
                         outbuffer = ByteBuffer.allocate((int)(inChannel.size()-position+1));

                  outbuffer.put(inbuffer.get());

                  while (outbuffer.hasRemaining()){

                        outChannel.write(outbuffer, position);

                        if(position+inbuffer.capacity()<inChannel.size()){
                              position = position + inbuffer.capacity();
                              System.out.println("next position : "+ position);
                        }
                        else{
                              position = position+1;
                              System.out.println("next position : "+ position);
                        }

                 }     



     outbuffer.clear();
              inbuffer.clear(); // do something with the data and clear/compact it.
          }

          inChannel.close();
          outChannel.close();
          infile.close();
          outfile.close();
