Observer Pattern in Java Explained | Behavioral Design Pattern Tutorial #java #designpatterns #code

The Observer Pattern is a fundamental behavioral design pattern in Java that establishes a one-to-many relationship between objects. It allows multiple objects (observers) to automatically receive updates whenever the subject (observable) changes state. This pattern is widely used in event-driven programming, publish-subscribe systems, and GUI applications. In this video, we will break down the Observer Pattern with a real-world example and a step-by-step coding implementation in Java to help you understand its core concepts and practical applications.

The Observer Pattern is extensively used in real-world applications, including event handling in Java Swing, stock market monitoring apps, notification systems, messaging services, and Model-View-Controller (MVC) architecture

If you’re preparing for a Java interview or looking to strengthen your design pattern knowledge, this tutorial is a must-watch! By the end of the video, you will have a clear understanding of how the Observer Pattern works, how to implement it in Java, and how it can be applied to real-world projects.
