 Choosing the right library is crucial. GroupDocs.Annotation for Java excels because it handles complex PDF manipulation behind the scenes while giving you fine‑grained control over annotation behavior.
 
+## How to create PDF highlights Java?
+
+AnnotationApi is the main entry point for loading and saving PDF documents in GroupDocs.Annotation. HighlightAnnotation represents a highlight markup that can be placed on a PDF page. Load your PDF with `new AnnotationApi().load("input.pdf")`, instantiate a `HighlightAnnotation`, set its rectangle coordinates, and call `annotationApi.add(highlight)` followed by `annotationApi.save("output.pdf")`. This three‑step pattern creates a visible highlight that conforms to the PDF specification and works in all major viewers.
