Abstraction in Java is a core Object-Oriented Programming (OOP) principle that focuses on hiding internal implementation details and showing only the essential functionality to the user. Why We Use Abstraction: Reduces Complexity: By hiding unnecessary technical details, abstraction makes large systems easier to understand, manage, and navigate. Enhances Security: It protects sensitive internal logic and data by only allowing users to access what is necessary through a public interface. Improves Maintainability: Changes to the internal code (the "how") do not break the rest of the application as long as the public abstract structure remains the same. Promotes Code Re-usability: It allows you to define common behaviors in one place (an abstract class) and share them across multiple sub classes. In Java, we use abstraction when we want to hide the complex implementation details of a system and only show the essential features to the user.…
