How does virtual functions work behind the scenes in Inheritance ? Does the compiler treat virtual functions specially ?
384
A virtual function or virtual method in an OOP language is a function or method used to override the behavior of the function in an inherited class with the same signature to achieve the polymorphism.
Every non-static method in Java is a virtual function except for final and private methods. The methods that cannot be used for the polymorphism is not considered as a virtual function. A static function is not considered a virtual function because a static method is bound to the class itself.
What Does Virtual Method Mean? A virtual method is a declared class method that allows overriding by a method with the same derived class signature. Virtual methods are tools used to implement the polymorphism feature of an object-oriented language, such as C#.
All methods by default are virtual in Java. Virtual Methods play important roles in Polymorphism because children classes in Java can override their parent classes' methods if the function being overriden is non-static and has the same method signature.
All methods in java are virtual by default. That means that any method can be overridden when used in inheritance, unless that method is declared as final or static.

'Virtual' is a C++ term. There are no virtual methods in Java. There are ordinary methods, which are runtime-polymorphic, and static or final methods, which aren't.
