Скачать или смотреть Understanding the Singleton Design Pattern in Java | Simple Explanation with Code Example

In this video, we’ll explore the Singleton Design Pattern in Java—one of the core design patterns every developer should understand. We'll cover the different approaches to implementing the Singleton pattern, including common techniques to ensure thread safety and performance.

You’ll learn:

What the Singleton pattern is and why it ensures only one instance of a class.
How to implement Eager Initialization Singleton, where the instance is created immediately.
The Lazy Initialization method, where the instance is created only when needed.
How Synchronized methods can ensure thread safety but may affect performance.
The Double-Checked Locking technique to optimize performance in multi-threaded environments.
Enum Singleton as a thread-safe, simple, and efficient way to implement the Singleton pattern in Java.

Step-by-step coding examples for each approach.
Why we use a private constructor and how it enforces the Singleton pattern.
By the end of this video, you will have a strong understanding of how to implement Singleton in Java, choose the best approach, and avoid common pitfalls. Whether you are a beginner or an experienced developer, this guide will help you use the Singleton pattern effectively in your projects.
