Thanks for the explanation.....
but I have a doubt
When you are going to modify a read stream(some time down the line), you
will be making the Fontable object with the name of Fonts. So it will be
the Fontable object that knows about the total count of bytes of sttbfffn.
So how can this info be filled into FIB from somewhere else??
Thanks & Regards

You don't need to create a new doc file. You only have to write the
FontTable to an HWPFFileSystem, then use that same file system to create
the
new FontTable. Look at the following code (assume that you already have a
FontTable object):
HWPFFileSystem sys = new HWPFFileSystem();
fontTable.writeTo(sys);
HWPFOutputStream tableStream = sys.getStream("1Table");
FontTable newFontTable = new FontTable(tableStream.toByteArray(), 0,
tableStream.getOffset());
//end of example
Also, you handle writing to the FIB in your FontTable class. Don't do this
because this will be handled somewhere else. You pass in an fcMin to the
writeTo function. This argument is unnecessary.
