Comments can be added to almost every element in Word, such as text, images, charts, tables, etc. This article focuses on how to add comments to selected text (phrase) in a Word document using Spire.Doc for Java.

Add a Comment to a Specific Phrase
The Paragraph.appendComment() method is used to add comments to an entire paragraph. By default, the comment mark will be placed at the end of the paragraph. To add a comment to a specific phrase, you need to place comment marks (represented by the CommentMark class) at the beginning and end of the text range. The following are the steps to add a comment to a specific phrase.
- Create a Document object, and load the sample Word file using Document.loadFromFile() method.
- Find the specific string from the document using Document.findAllString() method.
- Create a comment start mark and a comment end mark, which will be placed at the beginning and end of the selected phrase respectively.
- Create a Comment object, specifying content and author.
- Get the oner paragraph of the selected phrase, and add the comment to the paragraph as a child object.
- Save the document using Document.saveToFile() method.

//Find the paragraph where the string is located
Paragraph para = specificText.getAsOneRange().getOwnerParagraph();
//Get the index of the string in the paragraph
int index = para.getChildObjects().indexOf(specificText.getAsOneRange());
//Add the comment to the paragraph
para.getChildObjects().add(comment);
//Insert the start mark and end mark to the paragraph based on the index
para.getChildObjects().insert(index, commentmarkStart);
para.getChildObjects().insert(index + 2, commentmarkEnd);
//Save to file
doc.saveToFile("AddComment.docx", FileFormat.Docx_2013);
