Enforce super call on non constructor methods

Question

Is it possible to enforce an overriden method to call the superclass method? Constructors always need to call their superclass constructor. But i want to enforce this on normal methods, without the position of when it is called mattering.

Example:

public class A {

    public void doSth() {
        System.out.println("I must appear on console!");
    }

}

public class B extends A {

    @Override
    public void doSth() {
        System.out.println("Bla!");  // IDE should mark an error, because supermethod is not called.
    }

}

Although not strictly Java related, I was looking for an answer to this issue as it relates to Android and found the annotation in the support annotations library called "@CallSuper". It does exactly what you think, and throws a lint error if the subclass does not call the super's implementation of methods annotated with @CallSuper.

That solved my usecase, but again, I know that the solution is strictly tied with Android. Please let me know if that is too far off base and I will remove the answer.

Here is some more documentation on @CallSuper. https://developer.android.com/reference/android/support/annotation/CallSuper.html https://developer.android.com/studio/write/annotations.html (just search for CallSuper and it'll show right up in that second link.
