How can We set the footer on every page of pdf dynamically by using Java code

Question

I have a code that I am showing in PDF but, I want to set this content at the footer of pdf. The pages are created dynamically, which means the Page changes according to the content in the pdf. So I want to add this content in the footer and want the footer on every page of the pdf. Help me to solve this problem.
