  import org.apache.pdfbox.pdmodel.PDPage; 
  import org.apache.pdfbox.pdmodel.PDPageContentStream; 
  import org.apache.pdfbox.pdmodel.font.PDType1Font;  
  public class AddingTextToAPdf {  
     public static void main(String args[]) throws IOException {     
        
        //Loading an existing document 
        PDDocument doc = PDDocument.load(new File("C:/pdfBox/AddText_IP.pdf")); 
        //Creating a PDF Document 
        PDPage page = doc.getPage(0);       
        PDPageContentStream contentStream = new PDPageContentStream(doc, page); 
        
        //Begin the Content stream 
        contentStream.beginText(); 
        //Setting the font to the Content stream  
        contentStream.setFont( PDType1Font.TIMES_ROMAN, 16 ); 
        //Setting the position for the line 
        contentStream.newLineAtOffset(25, 725 ); 
        String text = "This is an example of adding text to a page in the pdf document. 
           we can add as many lines as we want like this using the draw string method 
           of the ContentStream class"; 
        //Adding text in the form of string 
        contentStream.showText(text); 
        //Ending the content stream 
        contentStream.endText(); 
        System.out.println("Content added");       
        //Closing the content stream 
        contentStream.close();      
        //Saving the document  
        doc.save(new File("C:/pdfBox/AddText_OP.pdf")); 
        //Closing the document  
        doc.close();  
     }  
  }
