Singleton Design Pattern In Plain English — With Real-Life Example

<p>The Singleton pattern is a design pattern in object-oriented programming that restricts the instantiation of a class to one object.</p> <p>What the hell does this mean?</p> <p>After reading multiple articles and watching some videos, I understand it enough to explain this concept better.</p> <p>The Singleton pattern is often used in situations where having multiple instances of a class could cause problems, such as managing shared resources, coordinating access to a centralized database, or controlling access to hardware devices. By restricting the instantiation of a class to a single object, the Singleton pattern helps ensure that all instances of the object share the same state and behavior.</p> <p>To implement the Singleton pattern, you typically define a class that has a private constructor and a static method that returns the single instance of the class. The static method first checks whether an instance of the class already exists; if it does, it returns that instance. If not, it creates a new instance and returns it.</p> <p><a href="https://levelup.gitconnected.com/singleton-design-pattern-in-plain-english-with-real-life-example-59edb2263c89">Website</a></p>
