Answer 1

Read from file or string to bytearray.

byte[] filedata = null;
String content = new String(bytearray);
content = content.replace("\r", "").replace("\uf8ff", "").replace("'", "").replace("\"", "").replace("`", "");
String[] arrOfStr = content.split("\n");
PDDocument document = new PDDocument();
PDPage page = new PDPage();
document.addPage(page);
try (PDPageContentStream cs = new PDPageContentStream(document, page)) {
    // setting font family and font size
    cs.beginText(); 
    cs.setFont(PDType1Font.HELVETICA, 14);
    cs.setNonStrokingColor(Color.BLACK);
    cs.newLineAtOffset(20, 750);
    for (String str: arrOfStr) {
        cs.newLineAtOffset(0, -15);
        cs.showText(str);
    }
    cs.newLine();
    cs.endText();
}
document.save(znaFile);
document.close();
