To fix the issue you can do I would like to do so something like this: , Your foo method receives a value of some type. Given
code :
void foo(FunctionalInterface func) {}
foo(SomeType::someMethod);
foo(() -> {});
foo(new SomeImpl());

this one helps. How can you reference an annotation as a code snippet properly in Javadoc? , IIRC,
code :
<code>
  &#64;Annotation public String field = "";
</code>
{@code 
  @Annotation public String field = "";
}
Why can't I use a getAnnotation() on a reference of Annotation?

I hope this helps . Your program seems to be working correctly. I get the following output when i run it...
code :
run-single:
Annotation Example 100 4.267
BUILD SUCCESSFUL (total time: 12 seconds)
final Annotation[] annos = m.getAnnotations();

for (Annotation anno : annos) {
    if (anno instanceof Hashingsnr) {
        final Hashingsnr impl = (Hashingsnr)anno;
        System.out.println(impl.str() + " " + impl.yuiop() + " " + impl.fdfd());
    }
}

this will help I connect annotation with UITapGestureRecognizer. I want to detect touch. , Change:
code :
-(void) calloutTapped:(id) sender
-(void) calloutTapped:(UITapGestureRecognizer *) sender
 -(void) calloutTapped:(id) sender {
    UITapGestureRecognizer *tapGesture = (UITapGestureRecognizer *)sender;
    MKAnnotationView *sendersView = (MKAnnotationView *)tapGesture.view;
    id<MKAnnotation> annotation = sendersView.annotation;
}

seems to work fine An instance of the annotation only exists for an annotated type/method. This is how you can get it
code :
Annotation requiresPermissionAnnotation = SomeAnnotatedClass.class.getAnnotation(RequiresPermissions.class);
RequiresPermissions requiresPermissions = (RequiresPermissions) requiresPermissionAnnotation;
RequiresPermissions requiresPermissions = SomeAnnotatedClass.class.getAnnotation(RequiresPermissions.class);
Annotation requiresPermissionAnnotation = someMethodInstance.getAnnotation(RequiresPermissions.class);
