Introduction

In Object-oriented languages, method is a subroutine which associates with the instances of the class to define the specific behavior of this class. In the inheritance of these languages, methods reimplementation is essential because descendant class inherited from the ancestor class in which properties and method have been defined to some extent. With the method reimplementation, coding can be more efficient and simple without rewriting the same code again and agian. However, in different OO languages, the ways of acquiring or allowing method reimplementation are significantly different. In this article, we are going to introduce these differences and provide code for better understanding.
