Principles

Inheritance Allows a class to inherit methods and properties from another class. Polymorphism Enables a single interface to operate on different types. Abstraction Focuses on essential characteristics, hiding implementation. 🎯 Goals of These Principles Improve modularity Enhance code reuse Simplify maintenance Align software design with real-world modeling 🧪 Java in Action interface Vehicle { void start(); } class Car implements Vehicle { public void start() { System.out.println("Car started"); } } This example combines: ...
