New Post: Adding headers to Word documents

Anyone know the difference between a XWPFParagraph and a XWPFParagraph() as a data type?
It would seem to imply an array of some kind...

Example I understand:
//creates a paragraph
XWPFParagraph paragraph = document.createParagraph();

Unsure:
XWPFParagraph p1 = new XWPFParagraph(ctP1);
XWPFParagraph[] pars = new XWPFParagraph[1];
pars[0] = p1;

How do I convert a XWPFParagraph to a XWPFParagraph() requested by headerFooterPolicy.createHeader(STHdrFtr.DEFAULT, newparagraphs)?
