将对非重写派生类方法的方法引用传递到其基类是否合法且已定义？

class BaseClass {
    public void nonOverriddenMethod() {
        System.out.println("This is a non-overridden method in the base class.");
    }
}

class DerivedClass extends BaseClass {
    @Override
    public void nonOverriddenMethod() {
        System.out.println("This method is overridden in the derived class.");
    }
}

public class Main {
    public static void main(String[] args) {
        BaseClass base = new DerivedClass();
        base.nonOverriddenMethod(); // Output: "This method is overridden in the derived class."
    }
}
