Underlining is a familiar way to draw attention to important words, sentences, or sections in a document. Unlike highlighting, an underline keeps the original text appearance largely unchanged. It gives readers a clear visual cue about content that deserves attention. This feature becomes useful when reviewing reports, editing business documents, or marking sections that need follow-up. In this guide, you’ll explore how to add underline annotations to DOC files in Java applications using the cloud-based REST API. You don’t have to worry about platform-related constraints and can annotate Word documents from any supported environment, desktop or web application.

Steps to Add Underline Annotations to DOC Files in Java

1. Download the GroupDocs.Annotation Cloud SDK for Java and create a new project
2. Obtain your API credentials and set them up using the Configuration class
3. Initialize AnnotateApi and add the input DOC file with FileInfo
4. Configure the underline annotation properties with AnnotationInfo
5. Apply annotation-related options such as the output file using AnnotateOptions
6. Request to add an underline annotation to Word using the annotate() method

To start the annotation process, set up the Cloud SDK. Select the input DOC file and identify the page and text area where the underline should appear. Apply the desired position and styling to the annotation. Send a request to add an underline annotation to the DOC file using the Java REST API. After the annotation is placed, you can save the updated DOC file for further review. Underline annotations provide a straightforward way to make important content easier to notice in word-processing files. They can be used for document review, reports, and internal business communication. The annotations draw attention to selected text rather than replacing it, enabling readers to quickly identify areas that require consideration while keeping the document content intact.

Code to Add Underline Annotations to DOC Files in Java

Adding underline annotations to DOC files is an excellent option to mark significant text without altering the underlying document content. You can integrate the capabilities of the GroupDocs.Annotation Cloud Java SDK and point readers toward important statements or sections that require attention. For teams working with shared documents, this functionality can make review conversations easier. A reader can underline a specific passage and leave the surrounding content unchanged. Using the Java REST API, developers can update their document annotation apps and mark text in Word documents with underlines to boost document workflows across various platforms.
