A real-world example of inheritance is a mother and child. That said, the way you interact with the either stl container is thanks to abstraction, both the list and the vector can for instance be traversed in the same way using similar methods (iterators). And now though you have designed only an abstraction of the university, you are not required to put abstract in your class declaration. Encapsulation is a related technique for hiding the implementation details of an object from other objects and from the programmer. Abstraction is related to "why" I am encapsulating it the first place. Many programmers have been wondering about this. What does puncturing in cryptography mean. Abstraction is just opposite of Encapsulation. This also gives an advantage because the setters give us complete control in setting the value to the attribute and help us to restrict the unnecessary changes. After the bird class is implemented, if we wish to create a pigeon, then we simply inherit the above Bird class. encapsulation is all about protecting invariants and hiding of implementation details. hides it from you" actually that is why I would say that the automatic vs. manual transmission on cars is a good example for ENCAPSULATION! Convention denotes the new class as child class, and the one that it inherits from is called parent class or superclass.If we refer back to the definition of class structure, we can see the structure for basic inheritance is class ClassName(superclass), which means the new . Untitled Document. For example, if a pigeon is created(born) with a grey colour, it doesnt change until the pigeon dies.

Encapsulation: Now, we have defined the properties of the bird class and the attributes which the birds have like colour, wings, legs can be initialized by creating an object of the bird class.

For example, the interface List in the standard library is an abstraction for a sequence of items, indexed by their position, concrete examples of a List are an ArrayList or a LinkedList. (this is an example of abstraction). Therefore, abstraction means the art of representing the essential features without concerning about the background details. It saves you from re-writing those functionalities that you have written somewhere else. Each other using abstract view, abstraction and encapsulation is achieved.

So you contacted Ferrari company and some chief mechanic came to your home and repaired it(Since your car is under warranty, your pocket is still big :-))This is a real time example for the above mentioned OOP's concepts, How? no i don't have a link, this is how I have understood it from various books like Code Complete. Then also i am talking abstract but at bit lower level as phone can be of As an example, at the top might be an interface with a single method, then the next level, provides several abstract classes, which may or may not fill in some of the details about the top level, but branches by adding their own abstract methods, then for each of these abstract classes are concrete classes providing implementations of all the remaining methods. Thus, triangle, there is a lot of duplicated code between both objects. It will encapsulate or put everything into one thing and provide others to use it. Why is proving something is NP-complete useful, and where can I use it? member, I googled again and again and none of the results seem to give me a proper answer. Inheritance: is more of a coding-trick than an actual principle.
