Polymorphism, in C#, is the ability of objects of different types to provide a unique interface for different implementations of methods. It is usually used in the context of late binding, where the behavior of an object to respond to a call to its method members is determined based on obje...
Polymorphism works by creating a relationship between classes using inheritance. When a superclass defines a method, its subclasses can override that method to provide their own implementation. At runtime, the appropriate method is called based on the actual type of the object. This dynamic binding...

Exception handling in C++ is a mechanism that allows a program to handle errors or exceptional situations during runtime by using try, catch, and throw statements.
Interfaces in C # provide a way to achieve runtime polymorphism.public interface IPayment{ void MakePayment(string a, int b=0);}public class PayPay : IPayment{ public void MakePayment(string a); // it needs only one parameter}public class Google : IPayment{ public void MakePayment(string...
This is called type erasure, which is a kind of runtime polymorphism. This typically implies a small performance penalty, similar to that of a virtual function call. Exercise: 1234567891011121314151617181920212223242526272829 #include <functional> struct A { int f() const { ...
8.When we call objective c is runtime language what does it mean? 我们说的oc是动态运行时语言是什么意思? 答案:多态。 主要是将数据类型的确定由编译时,推迟到了运行时。 这个问题其实浅涉及到两个概念,运行时和多态。 简单来说,运行时机制使我们直到运行时才去决定一个对象的类别,以及调用该类别对象指...
Using the function pointer, we can create an illusion of polymorphism. This concept is useful where we need to runtime polymorphism. To accomplish this task we need to create a function pointer within the structure and initialize the function pointer with the corresponding function. ...

However, Multiple Inheritance in Java is achieved by Interface. We will discuss it in the further article. This was all about Inheritance in Java. It is one of the ways to achieve runtime polymorphism in Java. Please share your questions and feedback by using the comment area below. We ar...
