Singleton Design Pattern is a type of Creational type Pattern. Singleton Design Pattern is used when we want to ensure that only one object of a particular class is instantiated. This single instance is used to
But the singleton pattern has a side effect that's often the true reason for adopting the singleton pattern,global access. But having global access to the singleton object is no more than a side effect of the singleton pattern. Unfortunately, many developers use the singleton pattern to have e...
This design pattern is often employed when there is a need to have a single, shared instance that can be accessed globally within the application.Difference between static class and singleton patternSingleton objects are stored in Heap, but static objects are stored in stack. We can clone the ...

It is worth noting that the Runtime class is declared as final, preventing it from being subclassed, and its default constructor is private, which means it cannot be instantiated directly.The Runtime class adheres to the Singleton Design pattern, ensuring that only one instance exists throughout...
What is a Structural Pattern?Structural patterns, within the context of the Gang of Four (GoF) design patterns, are a category of design patterns that deal primarily with the composition of classes and objects. They dictate how the entities should be composed to form larger structures in an ...
Singleton is one type of Java design pattern in Creational patterns. The main advantage of this pattern is, it is going to return the same object when you called this class. The advantage of this class is, 1)It is not required to create a object for this class to access i.e when you...
