Encapsulation

• What is Encapsulation? #1

  • Encapsulation in object-oriented programming is the practice of bundling data (attributes) and methods (functions) together within a class 
  • Using encapsulation ensures that data remains secure and is not accidentally modified or misused by controlling access to them using access modifiers (e.g., public, private) 
  • It also helps to organize code by keeping related data and methods together within an object 
• • Encapsulation #2
  • Encapsulation promotes code reusability, which means the same object or class can be used in different parts of a program without rewriting the code 
  • Encapsulation uses a concept called “Abstraction” which reduces complexity by hiding the implementation details of the object, making it easier to understand and work with 
  • Programmers can use methods and classes from other parts of the program without having to understand how that it has been constructed internally 
• Encapsulation in Classes 

  • Private variables are only accessible within the class itself, and external code cannot access them directly. 
  • Encapsulation hides how things work inside a class from the outside. External code can interact with the class using public methods without needing to understand its internal details
