Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called.

What is a protected method?

A protected method is like a private method in that it can only be invoked from within the implementation of a class or its subclasses. It differs from a private method in that it may be explicitly invoked on any instance of the class, and it is not restricted to implicit invocation on self .

Is it possible to override protected method to private?

Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier.

Can constructor be overridden?

Constructors are not normal methods and they cannot be “overridden”. Saying that a constructor can be overridden would imply that a superclass constructor would be visible and could be called to create an instance of a subclass.
