] | This is just not how inheritance works in Java.
If a method is overridden, and the overridden method is not visible, it's a compile-time error to try and call it.
You seem to expect that Java would automatically fall back to the method in the super class, but that does not happen.

```
class A{
protected void f(){
SOP("A");
}}
class B extends A{
protected void f(){
SOP("B");
}
public static void main(String...args)
{
B b=new B();
b.f();
}
}
```

] | The problem is that at compile time you are telling Java that you want to access a protected member of a class when you do not have such access.
If you did this instead;
```
A a = new B();
a.test();
```
Then it would work and the overridden method will run because at compile time Java checks that you have acces... | Yes, overriding the protected method is possible.
