A DESCRIPTION OF THE PROBLEM :
my code is follow:
public interface IFly {

    String fly1();

    Object fly2();
}

public class FlyImpl implements IFly {
    @Override
    @FlyEnable
    public String fly1() {
        return null;
    }

    @Override
    @FlyEnable
    public String fly2() {
        return null;
    }
}

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
@Documented
public @interface  FlyEnable {
}

public class Main {
    public static void main(String[] args) {
        //out 3, but i want 2
        //com.zj.IFly.fly2 should not be count
        System.out.println(FlyImpl.class.getDeclaredMethods().length);
        //is this is a bug? if this is not a bug, what should i do, then it out 2.

        for(Method method: FlyImpl.class.getDeclaredMethods()){
            if( method.isAnnotationPresent( FlyEnable.class)){
                // this out 3 times, but i want 2
                // com.zj.IFly.fly2 call isAnnotationPresent( FlyEnable.class) should not return true
                System.out.println("method:" + method.getName() + " is annotated by FlyEnable");
                //is this is a bug? if this is not a bug, what should i do, com.zj.IFly.fly2 call isAnnotationPresent( FlyEnable.class) return false
            }
        }
    }
}

i'm not good at English, 
If I say something wrong, don't be angry.
