The class to which the object belongs is like a template for all of its objects. This hierarchical arrangement controls complexity. You don't even have to know how they do what they do in order to use them properly. Finally, there is the quality of polymorphism. In traditional programming, to get two different tasks done requires writing two different functions.
Objects pass third-grade IQ tests.
Some experts say that OOP more clearly resembles the way humans think than other traditional ways of programming. Similar objects are grouped in classes. A class is a template that is used for building the smaller units-the objects that share the same kind of data and operations. A hierarchy is composed of classes that share interfaces through inheritance. The advantages of OOP are significant.
