//Add a section
Section sec = document.addSection();
//Add a paragraph
Paragraph paragraph = sec.addParagraph();
paragraph.appendText("Here is a paragraph with various character styles. This is ");
//Append text to the paragraph and return a TextRange object
TextRange tr = paragraph.appendText("text with strikeout");
//Set the character format to strikeout via TextRange object
tr.getCharacterFormat().isStrikeout(true);
//Apply shadow effect to text
paragraph.appendText(". This is ");
tr = paragraph.appendText("text with shadow");
tr.getCharacterFormat().isShadow (true);
//Set font size
paragraph.appendText(". This is ");
tr = paragraph.appendText("text in a large font size");
