Moreover, object types map directly into classes defined in object-oriented languages such as C++. Now your programs can better reflect the world they are trying to simulate. Structure of an Object TypeLike a package, an object type has two parts: a specification and a body (refer to ...
As shown in the above figure, there are five types of inheritances in Object-Oriented programming as described below: #1) Single Inheritance:When a derived class or subclass inherits from only one base or superclass then it is a single inheritance. #2) Multilevel Inheritance:In Multilevel Inh...

A behavioural theory of object compatibility is presented, which has implications for object-oriented regression testing. The theory predicts that only certain models of state refinement yield compatible types, dictating the legitimate design styles to be adopted in object statecharts. The theory also ...
