Step1: Create a empty PDF document using PDDocument class
Step2: Create a page based on your requirement. PDPage has more options like A4,A3 etc

Step3: ContentStream is used to write text inside the document. It uses the x axis and y axis concept to place text in the Document
Step4: close the stream and save the document inside your hard disk and close the document
