How to align a Chunk Left and Right Side

问题

i want to align the Chunk Left and Right side. Also the each Chunk have different format you can see in image.

i try the below code:

Chunk invoiceid = new Chunk("Invoice ID: ", font9BoldDARK_GRAY);
Chunk invoiceidvalue = new Chunk("value from database", font10NoramlBlack);
Chunk inoicdate = new Chunk("Invoice Date: ", font9BoldDARK_GRAY);
Chunk inoicedatevalue = new Chunk(new SimpleDateFormat("MMMM dd yyyy").format(new Date()), font10NoramlBlack);// get From database

    Paragraph invoiceParagraph = new Paragraph();
    invoiceParagraph.setTabSettings(new TabSettings(325f));
    invoiceParagraph.add(invoiceid);
    invoiceParagraph.add(invoiceidvalue);

    invoiceParagraph1.add(Chunk.TABBING);

    invoiceParagraph1.add(inoicdate1);
    invoiceParagraph1.add(inoicedatevalue1);
    invoiceParagraph1.setAlignment(Element.ALIGN_JUSTIFIED);
    pdfdocument.add(invoiceParagraph1);

which gives me result the Right side Chunk not in well format.

but i want align the like can you please help me.

The correct way to do this, is to use iText 7. Read chapter 3 of the building blocks tutorial to discover how to create a PDF that looks like this:

The code to achieve this, is amazingly simple:

public void createPdf(String dest) throws IOException {
    // create a low-level document
    PdfDocument pdf = new PdfDocument(new PdfWriter(dest));
    // create a high-level document
    Document document = new Document(pdf);
    // create a TabStop array
    List<TabStop> tabstops = new ArrayList<TabStop>();
    // don't forget to make a tab stop that aligns to the right
    tabstops.add(new TabStop(325, TabAlignment.RIGHT));
    // add paragraphs with Tab objects to the high-level document
    document.add(new Paragraph().addTabStops(tabstops)
            .add("Text to the left").add(new Tab()).add("Text to the right"));
    document.add(new Paragraph().addTabStops(tabstops)
            .add("ABCD").add(new Tab()).add("EFGH"));
    document.add(new Paragraph().addTabStops(tabstops)
            .add("01234").add(new Tab()).add("56789"));
    document.add(new Paragraph().addTabStops(tabstops)
            .add("iText 5 is old").add(new Tab()).add("iText 7 is new"));
    // close the document
    document.close();
}

Before you say I don't recognize that code, let me tell you that you are right: iText was completely rewritten. The code is now more intuitive to create, and easier to read.

Update: you are using the old iText 5 version that is no longer supported for free users (only for paying customers). As explained in the 2009 book "iText in Action - Second Edition", you created glue like this:

Chunk glue = new Chunk(new VerticalPositionMark())

You then used this glue in a Paragraph like this:

Paragraph p = new Paragraph();
p.add("Text to the left");
p.add(glue);
p.add("Text to the right");

This way, you can indeed avoid having to use tabs in iText 5.

this work for me:

Paragraph p = new Paragraph("some Text");
p.setAlignment(Element.ALIGN_RIGHT);
