Course Description

Object-oriented programming (OOP) is a powerful approach to writing organized and scalable software. Java, one of the world’s most popular programming languages, brings OOP to life with clear syntax and strong community support. In this course, you’ll learn how to use Java to model real-world systems using classes, objects, inheritance, encapsulation, and more.

Build Real-World Java Classes and Objects

Begin by learning to define classes as blueprints and use them to create object instances. You’ll apply core Java syntax to build reusable components that mirror real-world entities, like cars, passports, and formulas.

Add Behavior with Constructors and Methods

Master the use of constructors to initialize object state and explore methods to add behavior. You’ll write both void and return-type methods, helping you create dynamic and interactive programs.

Secure and Reuse Code with Encapsulation and Inheritance

Explore how access modifiers control what’s visible to users of your code. Learn how to use inheritance and abstract classes to eliminate duplication and create structured hierarchies.

Apply Interfaces and Polymorphism

Use interfaces to add flexibility and implement shared behavior across classes. Finally, unlock the power of polymorphism by overriding and overloading methods for more adaptable software designs.

By the end, you’ll be able to design modular Java applications with clean, object-oriented architecture.
