How is abstraction used in computer science?
In software engineering and computer science, abstraction is a technique for arranging complexity of computer systems. It works by establishing a level of complexity on which a person interacts with the system, suppressing the more complex details below the current level.
What is abstraction and its types?
Abstraction can be of two types, namely, data abstraction and control abstraction. Data abstraction means hiding the details about the data and control abstraction means hiding the implementation details. In object-oriented approach, one can abstract both data and functions.
What does abstraction mean?
: the act of obtaining or removing something from a source : the act of abstracting something. formal : a general idea or quality rather than an actual person, object, or event : an abstract idea or quality.
What do u mean by encapsulation?
Encapsulation is one of the fundamental concepts in object-oriented programming (OOP). It describes the idea of bundling data and methods that work on that data within one unit, e.g., a class in Java. This concept is also often used to hide the internal representation, or state, of an object from the outside.
What are the features of encapsulation?
Encapsulation is one of the fundamentals of OOP (object-oriented programming). It refers to the bundling of data with the methods that operate on that data. Encapsulation is used to hide the values or state of a structured data object inside a class, preventing unauthorized parties’ direct access to them.
What is the difference between abstraction and inheritance?
The main difference between abstraction and inheritance is that abstraction allows hiding the internal details and displaying only the functionality to the users, while inheritance allows using properties and methods of an already existing class. Object-Oriented Programming (OOP) is a major programming paradigm.
What are the main features of OOPs?
Features of OOPs:
- Classes.
- Objects.
- Data Abstraction.
- Encapsulation.
- Inheritance.
- Polymorphism.
What are the benefits of OOPs?
Advantages of OOP
- Re-usability. It means reusing some facilities rather than building them again and again.
- Data Redundancy.
- Code Maintenance.
- Security.
- Design Benefits.
- Better productivity.
- Easy troubleshooting.
- Polymorphism Flexibility.
What are the 5 OOP principles?
Following are the five concepts that make up SOLID principles:
- Single Responsibility principle.
- Open/Closed principle.
- Liskov Substitution principle.
- Interface Segregation principle.
- Dependency Inversion principle.
What is message passing in OOP?
Message passing is a form of communication between objects, processes or other resources used in object-oriented programming, inter-process communication and parallel computing. Synchronous message passing systems require the sender and receiver to wait for each other while transferring the message.
