The Singleton pattern ensures that a class has only one instance, offering a unified access point in software applications.It serves as a control tower, bringing order and efficiency by avoiding conflicts and resource waste.Unique Instance and Global Access Point are key features of the Singleton pattern.In daily life analogy, it resembles a unique landmark or a central post office for the software world.The pattern structure includes a private constructor, static variable, and static method for instance access.The UML class diagram visualizes the Singleton pattern's construction and uniqueness.Implementing the Singleton pattern involves creating a single instance for consistent behavior and data.A practical exercise demonstrates using Singleton for global state management, like a lighthouse guiding ships at sea.The Singleton pattern finds applications in configuration management, logging, thread pools, cache, and hardware access.To overcome Singleton pattern limitations, Dependency Injection is suggested for flexible testing and code improvement.
