How to use two different colors in a single String?

I want to set the color for only part of the string. How do I do this?

I have string like below, and I can't split the string.


String result = "Developed By : Mr.XXXXX";
I can create a paragraph in iText and set font with color like this:


Font dataGreenFont = FontFactory.getFont("Garamond", 10,Color.GREEN);
preface.add(new Paragraph(result, dataGreenFont));
It sets the green color to the entire text result but I want to set the color only for Mr. XXXXX part. How do I do this?

In iText 7 a Paragraph consists of a series of Text objects. A Text object is an atomic part of text in which all the glyphs are in the same font, have the same font size, color, etc...

Hence you need to split your String in two parts:

public static final String FONT_DIR = "src/main/resources/fonts/";

public void createPdf(String dest) throws IOException {
    PdfDocument pdfDoc = new PdfDocument(new PdfWriter(dest));
    Document doc = new Document(pdfDoc);

    FontProgramFactory.registerFont(FONT_DIR + "EBGaramond12-Regular.ttf", "Garamond");
    PdfFont garamond = PdfFontFactory.createRegisteredFont("Garamond", PdfEncodings.WINANSI, false);

    Text blackText = new Text("Developed By : ")
    Text greenText = new Text("Mr.XXXXX")

    Paragraph p1 = new Paragraph();
