Java Class Encapsulation

This lecture covers the fundamentals of encapsulation in Java classes, including defining public and private elements, designing a class like 'Rectangle' with specific attributes and methods, and implementing encapsulation principles to protect internal details while providing external access. Examples demonstrate how to interact with the class, modify internal implementations without impacting external users, and enforce data protections. The lecture also explores the perspective of a programmer using the 'Rectangle' class, showcasing how to declare, initialize, and utilize objects of this type.
