Oriented Object Design in the Java Language : Principles & Real-World Application
Object-oriented planning in Java revolves around key principles : encapsulation , extension , and polymorphism . Encapsulation promotes bundling information and functions within a blueprint , protecting direct modification. Inheritance provides creating new classes based on existing ones, encouraging re-application. Polymorphism permits objects of different categories to be processed as objects of a shared type . For example, building a program like a game would involve creating entities such as User , Object , and Level , where connections between them are set through methods and inheritance trees. This methodology leads to simpler to manage and adaptable software.
