SINGLETONS Meaning and
Definition
-
Singletons refer to objects that are designed to have only one instance in a program. In software development, a singleton is a design pattern that ensures a class can only be instantiated once, providing a global point of access to its instance throughout the entire application.
The primary purpose of using singletons is to guarantee that there is a single instance of a class, which can be beneficial for resource management, efficiency, and maintaining consistency within an application. By preventing multiple instances, singletons help control access to shared resources and facilitate communication between different components of an application.
Singletons typically involve a private constructor, which restricts external instances, and a static method or property that returns the single instance of the class. This method or property checks if an instance already exists and only creates a new instance if none exists. The single instance is stored as a static variable within the class.
While singletons provide benefits such as simplified access and resource sharing, they also have some drawbacks. They can create tight coupling between different parts of a program, making it harder to modify or test individual components. Additionally, improper use of singletons can lead to global state problems and make code less modular.
Overall, singletons are a design pattern that ensures there is only one instance of a class in a program, providing a globally accessible point of entry to that instance.

Etymology of SINGLETONS
The term "singleton" originates from the Middle English word "sengletoun" in the 14th century, which meant a single piece of anything. It was derived from the Old French word "sengle" meaning single. Over time, the term "singleton" came to be associated with individuals or objects that are unique or singular. In present usage, "singletons" commonly refers to individuals who are single or unmarried. Additionally, in computer programming, "singleton" refers to a design pattern where a class can only have one instance, and "singletons" is used to describe instances of such classes.
