Answer
Use isAnnotationPresent on elements like classes or methods.
Reflection allows you to examine annotations at runtime. The method isAnnotationPresent checks if a specific annotation is applied to a class, method, or field. For instance, you can verify if a method is annotated with @Deprecated to apply conditional logic based on this metadata.
