How do Java method annotations work in conjunction with method overriding?

Question

I have a parent class Parent and a child class Child, defined thus:

class Parent {
    @MyAnnotation("hello")
    void foo         


        

Answer 1

You found your answer already: there is no provision for method-annotation inheritance in the JDK.

But climbing the super-class chain in search of annotated methods is also easy to implement:

/**
 * Climbs the super-class chain to find the first method with the given signature which is
 * annotated with the given annotation.
 *
 * @return A method of the requested signature, applicable to all instances of the given
 *         class, and annotated with the required annotation
 * @throws NoSuchMethodException If no method was found that matches this description
 */
public Method getAnnotatedMethod(Class annotation,
                                 Class c, String methodName, Class... parameterTypes)
        throws NoSuchMethodException {

    Method method = c.getMethod(methodName, parameterTypes);
    if (method.isAnnotationPresent(annotation)) {
        return method;
    }

    return getAnnotatedMethod(annotation, c.getSuperclass(), methodName, parameterTypes);
}
