Reply rajajisubramanian says November 18, 2014 at 1:17 PM no its not a method overloading public static add(int a,int b)-its like a constructor description so its not a method and if For example: class A{} class B extends A{} A a=new B();//upcasting Example of Java Runtime Polymorphism In this example, we are creating two classes Bike and Splendar. So polymorphism means many forms. from below(answer) example you showd Dog as an Animal and hence it is polymorphism.

This stretches things a bit, but that's what is going on. –dasblinkenlight Dec 26 '13 at 10:36 @dasblinkenlight thanks for the info. public class StaticBindingTest { public static void main(String args[]) { Collection c = new HashSet(); StaticBindingTest et = new StaticBindingTest(); et.sort(c); } //overloaded method takes Collection argument public Collection sort(Collection c){ Targeted method call is resolved at compile time.

Dynamic binding/Run-Time binding/Late binding/Method overriding.(in different classes.) overloading example: class Calculation { void sum(int a,int b){System.out.println(a+b);} void sum(int a,int b,int c){System.out.println(a+b+c);} public static void main(String args[]) { Calculation obj=new Calculation(); obj.sum(10,10,10); I see only examples of shape, square, ...How do I load a user control dynamically in runtime?Let’s say there is a method that throws Null Pointer Exception in the super class. Method overloading and method overriding using instance methods are the examples for dynamic polymorphism. Compile Time Polymorphism In C++ This provides the ability to override functionality already available in the class hierarchy tree.

What change in history would I have to make to stop Christmas from happening? From java tutorial page : Subclasses of a class can define their own unique behaviors and yet share some of the same functionality of the parent class You can find good You can also see that truckVehicle.drive() results in a compile time error. Source And this is decided during the compile time.

This page may be out of date. Dynamic Polymorphism In C++ Type of object on which method is being invoked is not known at compile time but will be decided at run time. Each object reference can be used to invoke methods and the methods which can be invoked is decided based on the reference type.

Brought to you in partnership with IBM. http://evollux.net/polymorphism-in/compile-time-polymorphism-and-runtime-polymorphism-in-java.html In such scenario, compiler is able to figure out the method call at compile-time that's the reason it is known as compile time polymorphism.

method overriding is an example of run time/dynamic polymorphism because method binding between method call and method definition happens at run time and it depends on the object of the class In the example given below, both the classes have a datamember speedlimit, we are accessing the datamember by the reference variable of Parent class which refers to the subclass object. As runtime decision can be made compile/static time if we know the process already and with user inputs.
