itext pdf header signature not found

I am trying to split a PDF into multiple PDF. (ex)Each page to a separate PDF.

While searching, I got these links , regarding splitting PDF into multiple PDF files.

I tried to split a PDF into 2 PDF files.
Say I have 'N' no. of pages in a PDF.

Let M=N/2

Now Pages from 1 to M will be stored in one PDF file
Pages from M+1 to N will be stored in second PDF file.

When I run the code, I got this error.

PDF header signature not found.

After going through forums, at last I got a solution at this link.

Earlier my code contained,

                        PdfReader inputPDF = new PdfReader(InputStream);
Where InputStream is of FileInputStream class Instance.

I replaced the reader part with,
                        PdfReader inputPDF = new PdfReader(FileName);

Where FileName is of String Class

Atlast, this solved my issue.
