Method overriding is run
time polymorphism, because method of which class will be called is determine at run time.

Compile Time Polymorphism in Java is when you have the several methods with same name and different parameters and compiler has to decide how to select which method has to run based on the arguments hence the name Compile time polymorphism or method overloading.

In run time polymorphism compiler doesn't know about way of execution of program that mean decide way of execution at run time while in compile time polymorphism compiler know about the way of execution of program. Example : compile time polymorphism -- method overloading run time time polymorphism -- method overriding

• Compile time Polymorphism also known as method overloading • Method overloading means having two or more methods with the same name but with different signatures LEarn Design Pattern,C#,ASP.NET,LINQ,Sharepoint,WCF,WPF,WWF

dynamic method dispatch is a technique by which a call to a overridden method is solved at runtime rather than compile time..this is how java implements runtime polymorphism.

Yes. Method Overloading is a form of Polymorphism

Runtime polymorphism is also called as method overriding, late binding or dynamic polymorphism. It is when a method in a subclass overrides a method in its super class with the same name and signature.

Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet extends java.util.HashSet. The method add() is overridden in LinkedHashSet. If you have a variable that is of type HashSet, and you call its add() method, it will call the appropriate implementation of add(), based on whether it is a HashSet or a LinkedHashSet. This is called polymorphism. Method overloading is defining several methods in the same class, that accept different numbers and types of parameters. In this case, the actual method called is decided at compile-time, based on the number and types of arguments. For instance, the method System.out.println() is overloaded, so that you can pass ints as well as Strings, and it will call a different version of the method. Overriding is an example of run time polymorphism. The JVM does not know which version of method would be called until the type of reference will be passed to the reference variable. It is also called Dynamic Method Dispatch. Overloading is an example of compile time polymorphism.

Yes. Method Overriding is a form of Polymorphism.Overridden MethodsAny time you have a class that inherits a method from a superclass, you have the opportunity to override the method (unless, as you learned in the earlier chapters, the method is marked final). The key benefit of overriding is the ability to define behavior that's specific to a particular subclass type. The following example demonstrates a Porsche subclass of Car overriding the Car version of the drive() method:public class Car {public void drive() {System.out.println("Generic Car Driving Generically");}}class Porsche extends Car {public void drive() {System.out.println("Porsche driving Full Throttle");}}

In C++, overriding and function, method, or operator is a different thing than (dynamic) polymorphism, so overriding a polymorphic method is almost entirely possible.

Polymorphism is used in Java when we want multiple things to represent the same entity. The usage definition might be misleading but, powerful features like Method Overloading and Method Overriding can be used to tap the potential of polymorphism in Java and implement complex functionalities with ease.

Overriding is an Object-Oriented concept where a subclass overrides a parent class's method(s) so it can provide it's own implementation.

Overriding is closely connected to polymorphism. Redefining method is similar to Overriding but you cannot expect those redefined methods to deliver polymorphism.The concept of redefining is used when it involves static methods.

No. Interfaces in Java are a construct to get polymorphism ( subtype polymorphism ) working in Java, but they are not a "kind" of polymorphism. In polymorphism happens when two objects respond to the same message ( method call ) in different way ( hence poly -> many, morphism -> way or shape : polymorphism -> many ways). In Java to be able to send the same message to two different objects you have to either inherit the same parent, or implement the same interface.

The dictionary definition of polymorphism refers to a principle in biology in which an organism or species can have many different forms or stages. This principle can also be applied to object-oriented programming and languages like the Java language. Subclasses of a class can define their own unique behaviors and yet share some of the same functionality of the parent class.Overriding and Overloading are two techiques to achive polymorphism in Java.Method overloading: When a method in a class having the same method name with different arguments is said to be method overloading. Method overriding : When a method in a class having the same method name with same arguments is said to be method overriding.

Polymorphism is used whenever you wish to achieve specific behaviour from a generic object, where the object's actual type may not be known or would be impossible to determine at compile time. By declaring virtual methods in the generic type (the base class), and overriding them in the derived type, you ensure that the derived object does "the right thing" regardless of its actual type, and regardless of whether the method is called directly or indirectly via the base class. With polymorphism, there is no need to determine the actual runtime type of the object, you get that for free simply by calling the appropriate virtual methods.

A method known as RFLP (restriction fragment length polymorphism) analysis can be used to make a DNA fingerprint.

Polymorphism is the method in which a java program can have more than one function(or method) with the same name but different method signatures(different parameters or return type). possible allowance: void s() void s(int a) void s(int a,int b) void s(float a) int s()

Yes they can. This is the fundamental feature of polymorphism and is called method overloading. Where you have multiple methods with the same name in a class. These methods differ from one another in the method signature alone.

Dynamic polymorphism is a programming method that makes objects with the same name behave differently in different situations. This type of programming is used to allow Java Scripts to run while playing a game on the computer, for example.

A method is simply a name we often use when referring to a virtual function in object oriented programming. We can define virtual functions for any class method which we expect to be overridden by a derivative of the class. Even if the exact runtime type of an object is not known but we hold a reference or pointer to one of its base classes, and unless we specify otherwise, implicitly invoking any method of that base class will invoke the most-derived override of that method, thus objects behave according to type even when that type is not known at compile time. This is known as runtime polymorphism.

Polymorphism in VC++ is the same as polymorphism in C++ itself. When you implicitly call a virtual method of a base class or one of its derivatives, then you rightly expect the most-derived override to execute instead, even when the runtime type is completely unknown to the caller and cannot be determined at runtime let alone compile time. You get that for free simply by overriding the known virtual methods of the base class, and without any need for expensive runtime type information, which is only useful if the caller is actually aware of the type in the first place, and which can only be predicted on a closed system. The whole point of polymorphism is that the base class (and therefore the caller) need know nothing whatsoever about any of its derivatives in order to execute more specialised methods. VC++ fully supports this aspect of OOP.

In computer science, polymorphism refers to a computer language's ability to process objects according to their data type. Dynamic binding on the other hand, is a mechanism wherein the method used on an object is being looked up by name at runtime.

Virtual method invocation is a term borrowed from C++. It means that methods are invoked polymorphically. Instead of invoking the method in the compile-time type, the method is invoked as its runtime type. In C++, you declare methods virtual that are executed this way.

Inheritance is the object oriented feature by which the functionality and features of one class are made available to another class without having to copy paste the code. Polymorphism is the object oriented feature by which multiple methods of a class can coexist with minor differences. Ex: method overloading.

When the method call is resolved at compile time, it is called as static binding, when the method call is resolved at run time then it is called as dynamic binding. In method overriding, the overridden method call is resolved using dynamic method dispatch(i.e it is resolved at run time).
