Module Description

This module introduces students to the concept of classes and objects, the foundation of Object-Oriented Programming (OOP) in Java. Students will learn how to define their own Java classes, create objects (instances), and understand how data (fields) and behavior (methods) are encapsulated within a class. This module builds the foundation for applying OOP principles such as encapsulation, inheritance, and polymorphism in later modules.

Learning Objectives

By the end of this module, students will be able to:

-Understand the difference between classes and objects.

Define their own classes with fields (attributes) and methods (behaviors).

Create and use objects from a class using the new keyword.

Use constructors to initialize object data.

Apply the concept of encapsulation through access modifiers (public, private).

Use the this keyword to refer to the current object.
