The Decorator Pattern is a flexible alternative to subclassing for extending functionality. It allows behavior to be added to individual objects without affecting the other objects from the same class. It is particularly helpful when changes are needed during runtime. Also, it’s helpful when subclassing would result in an exponential Read more…
We use the Prototype Pattern when creating new instances from scratch is more expensive than copying existing ones. So, instead of instantiating new objects, you can have a prototype from which clones/copies are made. Traditional approach in Java In this Java example, GraphicElement represents a complex graphic element with complex initialization logic, Read more…
The Builder pattern is a design pattern used to construct complex objects step by step. It separates the construction of an object from its representation, allowing the same construction process to create different types. When creating complex objects, direct construction using constructors might involve many parameters, leading to unclear code Read more…
The Singleton pattern is a design pattern that ensures a class has only one instance, while providing a global point of access to it. This pattern is used when exactly one object is needed to coordinate actions across the system. This is useful in scenarios like configuration managers, where a Read more…
In the evolving world of back-end development, the choice of programming language plays a pivotal role in defining the efficiency, expressiveness, and overall experience of a developer. Kotlin, a modern language that interoperates seamlessly with Java, has emerged as a game-changer. Why is this transition important? It’s because Kotlin offers Read more…
