OOPs (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.

• OOPs focuses on creating objects that interact with each other to solve problems

• Key concepts include encapsulation, inheritance, polymorphism, and abstraction

• Encapsulation involves bundling data and methods that operate on the data into a single unit

• Inheritance allows one class to inherit properties and behavior from another class

• Polymorphism allows ob...read more

Encapsulation is the concept of bundling data and methods that operate on the data into a single unit.

• Encapsulation helps in hiding the internal state of an object and restricting access to it.

• It allows for better control over the data by preventing direct access from outside the class.

• Encapsulation also enables data to be accessed only through the methods defined in the class.

• Example: In a class representing a car, the variables like speed and fuel level can be encapsulated ...read more

Data structures are ways to organize and store data in a computer so that it can be accessed and manipulated efficiently.

• Data structures define how data is stored, accessed, and manipulated in a computer program.

• Examples include arrays, linked lists, stacks, queues, trees, and graphs.

• Choosing the right data structure is crucial for optimizing performance and efficiency in software development.

Regularity references and different approaches

• Regular references are important for consistency in work

• Different approaches allow for flexibility and creativity

• Examples: using templates for regular reports, trying new methods for problem-solving

Encapsulation is the process of hiding implementation details and providing a public interface for accessing the functionality.

• Encapsulation helps in achieving data abstraction and information hiding

• It prevents unauthorized access to the internal details of an object

• It allows for easier modification of implementation details without affecting the external interface

• Example: A bank account class may encapsulate the account balance and provide methods for depositing and withdraw...read more
