注解在接口中的方法，子类中不能查找到方法的注解
public class AnnotationTest implements A {
public static void main(String[] args) {
Method[] ms = A.class.getDeclaredMethods();
System.out.println(ms[1].getName()+" : "+ms[1].isAnnotationPresent(Annotation.class));
}
public void a() {
}
public void b() {
}
}
interface A{
void a();
@Annotation
void b();
}
class AnnotationDemo {
@Inherited
@Retention(RetentionPolicy.RUNTIME)
public @interface Annotation{
}
}
