This compile time polymorphism also called as early binding or method overloading. Do you need your password? The use of polymorphism ? Even though the compiler thinks it is going to call the walk method in chimp; but that is not what actually happens. this contact form
Because, in case of overloading, at compile time the compiler knows which method to link to the call. This is so even should the calling application be unaware that the object is an instance of the derived class. Ex wait(), notify(), equals(), etc. share|improve this answer answered Jan 28 '10 at 7:11 Max Shawabkeh 25.5k46474 add a comment| up vote 0 down vote Classical examples of static polimorphism are based on template metaprogramming or
vh=new Vehicle(); vh.move(); // prints Vehicles can move!! } } It should be noted that in the first call to move(), the reference type is Vehicle and the object being referenced Only constraint is that ONLY return type can't be different for a method to be overloading method.

Also is operator overloading supported by Java? Method overloading means having two or more methods with the same name but with different signatures. Runtime Polymorphism In C++
Overriding - same method names with same arguments and same return types associated in a class and its subclass. This means that greet() method is bound at compile time only.This is called as compile time polymorphism. In this kind of polymorphism, reference of class X can hold object of class X or an object of any sub classes of class X. http://evollux.net/polymorphism-in/what-is-the-difference-between-compile-time-polymorphism-and-runtime-polymorphism-in-java.html If not VMT (not virtual function), the called method would be the one of the compile-time class, but due to VMT a virtual method called during run-time will be the one
