java - Create a PDF according to a given format using the iText library -


i'm working on small project in java, there want fetch contents database , write them pdf file.

i tried googling , came itext library.

can guide create pdf looks enclosed image computer generated invoice

ps: i'm pretty new java.and it's first java project.

i've done quick implementation of of use-case.

here's code:
first define small class acts single record in invoice.

static class article{     int sno;     string description;     int quantity;     double unitprice;     public article(int sno, string description, int quantity, double unitprice)     {         this.sno = sno;         this.description = description;         this.quantity = quantity;         this.unitprice = unitprice;     } }

then i've created method each of big blocks in invoice.
starting title: 

public static void addtitle(document layoutdocument) {     layoutdocument.add(new paragraph("retail invoice").setbold().setunderline().settextalignment(textalignment.center)); }

then adding little paragraph of text that's underneath title:

public static void addcustomerreference(document layoutdocument) {     layoutdocument.add(new paragraph("m/s indian convent school").settextalignment(textalignment.left).setmultipliedleading(0.2f));     layoutdocument.add(new paragraph("y pocket-3, sector-24, rohini delhi-110085").setmultipliedleading(.2f));     layoutdocument.add(new paragraph("b 011-64660271").setmultipliedleading(.2f)); }

and adding table:

public void addtable(document layoutdocument, list<article> articlelist) {     table table = new table(unitvalue.createpointarray(new float[]{60f, 180f, 50f, 80f, 110f}));      // headers     table.addcell(new paragraph("s.n.o.").setbold());     table.addcell(new paragraph("particulars").setbold());     table.addcell(new paragraph("qty").setbold());     table.addcell(new paragraph("rate").setbold());     table.addcell(new paragraph("amount in rs.").setbold());      // items     for(article : articlelist)     {         table.addcell(new paragraph(a.sno+""));         table.addcell(new paragraph(a.description));         table.addcell(new paragraph(a.quantity+""));         table.addcell(new paragraph(a.unitprice+""));         table.addcell(new paragraph((a.quantity * a.unitprice)+""));     }      layoutdocument.add(table); }

the main method looks this:

public static void main(string[] args) throws filenotfoundexception {      pdfdocument pdfdocument = new pdfdocument(new pdfwriter("myfirstinvoice.pdf"));     document layoutdocument = new document(pdfdocument);      // title     addtitle(layoutdocument);      // customer reference information     addcustomerreference(layoutdocument);     addtable(layoutdocument, arrays.aslist(             new article(1, "envelopes",2000, 1.70),             new article(2, "voucher book", 50, 41)));      // articles     layoutdocument.close(); }
