Performance impact of using abstractions in object-oriented programming

The abstraction is a common mechanism that developers use when developing applications. It allows their code to be more robust and easier to maintain because it provides a loose coupling between application’s components. This paper analyses an impact of using abstractions on application execution and its performance. Tests were devised so that one can measure an execution time when only concrete classes are used, when interfaces or implementation are used and when abstract classes or inheritance are used. This paper also presents an analysis of a special case of using interfaces, in which the objects are not directly instantiated, but instead their creation is controlled by an Inversion of Control container.
