Java Singleton Pattern

The Singleton Design Pattern in Java ensures that a class has only one instance and provides a way to access it globally. While it solves the problem of having a single instance, it's essential to consider its use carefully, especially in multi-threaded environments, and weigh the advantages and disadvantages based on the specific application

Learn how to create a singleton class in Java using different approaches, such as eager, lazy, double-checked locking, Bill Pugh and enum. Also, understand the serialization effect and how to avoid it.

Java ensures that only one instance of an enum value is created, even in a multithreaded environment. The Enum Singleton pattern is the most robust and concise way to implement a singleton in Java. Many Java experts, including Joshua Bloch, recommend Enum Singleton as the best singleton implementation in Java.

Singleton design pattern is used in core Java classes also for example, java.lang.Runtime, java.awt.Desktop. Java Singleton Pattern Implementation. To implement a singleton pattern, we have different approaches, but all of them have the following common concepts. Private constructor to restrict instantiation of the class from other classes.

When to Use the Singleton Pattern in Java. Use the Singleton pattern when. There must be exactly one instance of a class, and it must be accessible to clients from a well-known access point When the sole instance should be extensible by subclassing, and clients should be able to use an extended instance without modifying their code
