Introduction to Object-Oriented Programming in Java

This lecture introduces the basic concepts of object-oriented programming in Java, starting with a comparison to imperative/procedural programming. It covers the principles of encapsulation and abstraction, emphasizing the importance of organizing complex programs. The lecture explains how objects group data and related operations, leading to better program visibility, coherence, and modularity. It also discusses the levels of perception of objects through encapsulation, highlighting the external interface and internal implementation details. The importance of abstracting and encapsulating is illustrated through examples, showcasing the benefits of separating internal and external levels in object usage. The lecture concludes with a summary of encapsulation and abstraction, emphasizing the role of interfaces in object-oriented programming.
