Answer
Reflection uses isAnnotationPresent to check for annotations.
Reflection allows you to inspect elements like methods to see if they have specific annotations. The isAnnotationPresent method on a Method object checks for the presence of an annotation. This is useful in a framework to trigger specific behaviors based on annotated methods, such as mapping a URL to a method.
