        sub.testSub();
    }
}

class Parent {

    protected boolean test() {
        throw new RuntimeException();
    }

    protected void testParent() {
        if (test()) {
            System.out.println(this.getClass().getName());
        }

}

class Sub extends Parent {

    public void testSub() {
        super.testParent();
