advantages and disadvantages of encapsulation in object oriented programming

As explained earlier, you can use the encapsulation concept to implement an information-hiding mechanism. Encapsulation is one of the big pillars that OOP is built on. As the names indicate, a getter method retrieves an attribute and a setter method changes it. It means that all of the object's data is contained and hidden in the object and access to it . The available quantity of a drink changes over time. Encapsulation also helps to reduce the complexity of an application, by hiding the implementation details from other parts of the code. To understand the difference, we need to understand the idea of abstraction. Inheritance is the process by which we can acquire properties and behavior of a class into another class. With the encapsulation, we provide security over the data and protect our data or, we can say, object from unwanted access by the user. When programmers step in to change it, the text eventually becomes disorganized and harder to follow. Techwalla may earn compensation through affiliate links in this story. Implementations of abstract data types, modules, and libraries, among other systems, also offer encapsulation. Programmers should use these access modifiers to differentiate between public and non-public interface of an object. By contrast, OOP programmers take new and existing software objects and "stitch" them together to make new programs. The default access modifier has no keyword. The main benefit of encapsulation is that we can hide the information from the user. Encapsulation creates explicit barriers between different abstractions and promotes clear separation of concerns. Encapsulation is a way to can restrict access to methods and variables from outside of class. Performing encapsulation is a great OOP practice, though its best when paired with a robust APM solution like Retrace for error monitoring. To master OOP a beginner must learn new, abstract concepts such as polymorphism -- reusing objects while adding new features to them -- and encapsulation -- hiding parts of an object's internal data to improve security -- neither of which ideas are found in older styles of programming. In object-oriented programming, there are four different types of access modifiers: The public access modifier has a broad scope. In this example, we create an Employee class by defining employee attributes such as name and salary as an instance variable and implementing behavior using work() and show() instance methods. It is a pretty ordinary situation if we do not use any other access modifier. Meaning.

The method of hiding details of a class is called abstraction. Now lets see the example of encapsulation in C++ to better understand the benefits of encapsulation as follows. Encapsulation suggests that one class must not have access to another classs (private) data. If we dont write public, private, or protected that means that the data structure has a default access modifier. Whenever we are working with the class and dealing with sensitive data, providing access to all variables used within the class is not a good choice. In the early days of computing, space on hard drives, floppy drives and in memory were at a . So encapsulation and abstraction work together to create a clear separation between the interface and implementation of a class, making it easier to understand and maintain the code. One of the main advantages of OOP is that it allows developers to create modular, reusable code. We usually come across the OOP term and its principles in languages like C# . This greatly simplifies the development process, as it allows developers to write code that is more generic and can be used in multiple contexts.

On this Wikipedia the language links are at the top of the page across from the article title. This is because inheritance creates a strong connection between classes, but weakens encapsulation within a class hierarchy. Ideally, interface is exposed in a way that is simple for other objects to understand, because for most problems, clients dont really care about implementation details. Encapsulation protects an object from unwanted access by clients. Encapsulation is one of the fundamental concepts in object-oriented programming (OOP), including abstraction, inheritance, and polymorphism. Note: To experience the power of encapsulation, one should know getter and setter methods. cout<
