Anabstractclass isincompletein its definition, since the implementation of itsabstractmethods is missing. Therefore, anabstractclasscannot be instantiated. In other words, you cannot create instances from anabstractclass (otherwise, you will have an incomplete instance with missing method's body). To ...
Runtimepolymorphism.Also known as dynamic polymorphism,runtimepolymorphism uses method overridingto let a child class have its own definition of a method belonging to the parent class.
