Java Open Source Tool Itext generates a simple instance of PDF _java

Itext download page: http://sourceforge.net/projects/itext/files/
1. Create a simple PDF file

Package console.pdf;
Import java.io.FileNotFoundException;

Import Java.io.FileOutputStream;
Import com.itextpdf.text.Document;
Import com.itextpdf.text.DocumentException;
Import com.itextpdf.text.PageSize;
Import Com.itextpdf.text.Paragraph;

Import Com.itextpdf.text.pdf.PdfWriter; /** * using Itext to generate PDF files/public class CreatePDF {public static void main (string[] args) {createpdf p001 = new Cr

    Eatepdf ();
    String filename = "p001.pdf";
  P001.createpdf (filename);
    public void createpdf (String filename) {//step 1 Document document = new document (PAGESIZE.A4);
      
      Step 2 try {pdfwriter.getinstance (document, new FileOutputStream (filename));
      Document.addtitle ("Id.net"); 
      Document.addauthor ("Dotuian"); 
      Document.addsubject ("This is the subject of the PDF file.");
      
      Document.addkeywords ("This is the keyword of the PDF file.");
      Step 3 Document.open (); Step 4 Document.add (New Paragraph ("Hello world!"));
    catch (FileNotFoundException e) {e.printstacktrace ();
    catch (Documentexception e) {e.printstacktrace ();
    finally {//Step 5 document.close ();

 }
  }

  
  
  
}

2. Add table in PDF file
