Encapsulation and Interface: Java Basics

This lecture introduces the concepts of encapsulation and interface in Java programming. Encapsulation ensures that the internal details of an object are hidden using private access modifiers, while interfaces provide a way to interact with objects externally through public methods. The lecture covers the importance of access rights, the use of accessors and mutators to manipulate private attributes, and the concept of shadowing in object-oriented programming. It also explains the role of 'this' keyword in resolving attribute ambiguity and discusses the memory management of objects in Java, emphasizing the use of references. Additionally, the lecture touches on the significance of handling null references when working with objects.
