If you have the source code: an annotation is declard as

@interface MyAnnotation { /* ... */ }

If you have some class object:

// Class<?> myClass = MyAnnotation.class;
if (myClass.isAnnotation()) { /* ... */ }

Maybe you can like this:

if(class.hasMethodAnnotation(Annotation.class)){}

You can try this for standard java: Class clazz =YourAnnotation.class; System.out.println(clazz.isAnnotation()); – Oliver Feb 16 '23 at 03:13
