Dec 26, 2013 · 8. Static Polymorphism: is where the decision to resolve which method to accomplish, is determined during the compile time. Method Overloading could be an example of this. Dynamic Polymorphism: is where the decision to choose which method to execute, is set during the run-time.
Jun 23, 2009 · With polymorphism, the CLR is able to infer the real type of the object we act on using what is called a virtual table. So it call the good method, and here calling Shape.Draw() if Shape is Point calls the Point.Draw(). So the code draws the shapes. More readings. C# - Polymorphism (Level 1) Polymorphism in Java (Level 2) Polymorphism (C# ...
The key difference between parametric polymorphism and overloading (aka ad-hoc polymorphism) is that parameteric polymorphic functions use one algorithm to operate on arguments of many different types, whereas overloaded functions may use a different algorithm for each type of argument. edited Oct 24, 2012 at 15:42.
Jul 31, 2012 · The kind of polymorphism related to inheritance is classified as inclusion polymorphism or subtype polymorphism. Wikipedia provides a good definition: In object-oriented programming, subtype polymorphism or inclusion polymorphism is a concept in type theory wherein a name may denote instances of many different classes as long as they are related by some common super class.
Jun 16, 2012 · 15. The reason why you use polymorphism is when you build generic frameworks that take a whole bunch of different objects with the same interface. When you create a new type of object, you don't need to change the framework to accommodate the new object type, as long as it follows the "rules" of the object.
Jun 10, 2011 · Polymorphism is an effect of inheritance. It can only happen in classes that extend one another. It allows you to call methods of a class without knowing the exact type of the class. Also, polymorphism does happen at run time. For example, Java polymorphism example: Inheritance lets derived classes share interfaces and code of their base classes.
Jan 21, 2015 · 1. If you use the subclass from an array that contains its superclass, then you have access only to the methods that are available in the superclass, as these are the methods common among all subclasses. private String hobby; public String getHobby() {. return hobby;
Jul 4, 2009 · 8. You can't cast objects in Java. You can cast references in Java. Casting a reference doesn't change anything about the object it refers to. It only produces a reference of a different type pointing to the same object as the initial reference. Casting primitive values is different from casting references.
May 8, 2018 · 9. Yes this is Runtime polymorphism in Java. In static polymorphism, compiler itself determines which method should call. Method overloading is an example of static polymorphism. In runtime polymorphism, compiler cannot determine the method at compile time. Method overriding (as your example) is an example of runtime polymorphism.
3. In simple term, Abstraction is conceptual and Poly is behavioral. In order to achieve abstraction in OOP, you need Poly. Abstraction in object oriented programming is a concept or design pattern I may say, which enables better isolation, loosely coupling thus testability, and reusability and extensibility.
