What kind of methods in Java do not behave polymorphically?

Abstract methods
Final methods
Public methods
Protected methods

The correct answer is: Final methods

Final methods in Java do not behave polymorphically because they cannot be overridden in the subclasses. Therefore, only the original method defined in the superclass will be executed, regardless of the subclass instance used to call the method. This means that the behavior of the method cannot be changed in different subclasses, making it non-polymorphic. Abstract methods, on the other hand, must be overridden in subclasses and therefore have multiple implementations, making them polymorphic. Public and protected methods can be overridden and have different implementations in subclasses, making them also behave polymorphically.
