How can you use encapsulation to create secure code?

Imagine a recipe book as an "interface" in a bakery. It lists ingredients and steps but not how to precisely bake. Different bakers ("classes") follow this recipe book, each creating their unique cakes. The book sets a common structure ("method signatures"), and bakers add their flair. This interface inheritance, like a shared recipe book, promotes consistency (ingredients and steps) across diverse cakes (classes), fostering a unified approach while allowing individual creativity in implementation.

So, interface inheritance is like having a standardized recipe book for diverse bakers. It ensures a consistent structure (ingredients and steps) while allowing each baker to bring their creativity and technique to the baking process. This promotes a shared understanding of what's needed (interface) while accommodating individual variations (implementation)

Interface inheritance is when one part of your code defines a set of methods (like a contract) without saying how they should work, and another part of your code agrees to follow this contract by implementing the methods as described.

Interface inheritance supports encapsulation by defining a set of methods that a class must implement, without specifying how they are implemented. Think of it as a contract that says what jobs a class can do, but not how it does them. This way, the internal workings of a class (how it does its jobs) are hidden behind the interface, further protecting the details and ensuring the class can interact with other parts of the code in a controlled manner.

Polymorphism is the ability to do things in many different ways. We achieve this by using two techniques: method overloading (doing similar things in different ways) and method overriding (changing the way things are done). It's like having multiple tools in your coding toolbox.

Polymorphism is a concept where you can use a single action to work with different types of objects. Think of it as a universal remote that can control your TV, air conditioner, and lights. Even though these devices are different, you use the same remote (action) to operate them in their unique way.

When polymorphism is used, it supports encapsulation by allowing the details of how a method is implemented to be hidden behind a common interface. This means that the internal workings of classes can change without affecting the outside code that uses them. So, polymorphism helps maintain encapsulation by letting objects interact in a generic manner, without needing to know the specifics about each other.

It has several benefits: 1. It makes the code safer by preventing outside code from directly changing internal data. 2. It simplifies the code, making it easier to understand,. 3. It allows for flexibility to change how things work internally without affecting other parts of the program that use the class. 4. It enhances the ability to debug, because you can control access and modification through a single point.

Encapsulation (Data Hiding): - The encapsulation contains : Setters, Getters and Constructor - The goal is for not making repetitive code - To share a data privately so you can share data in another class without sharing the private data

Encapsulation is a fundamental concept in object-oriented programming that involves bundling data with the methods that operate on that data. It serves as a protective barrier that prevents external entities from accessing the internal state of an object directly. By using encapsulation, developers can create a controlled interface for interaction with an object, which enhances security by allowing control over how and when data is modified. Encapsulation also promotes code maintainability and reduces complexity by decoupling the object's implementation details from its usage, making it easier to manage and evolve the codebase over time.
