The Flyweight Chronicles: How to Make Your Code Weightless!

The Flyweight Design Pattern is a structural pattern used to minimize memory usage or computational expenses by sharing as much as possible with related objects. It is beneficial when many similar objects need to be created, and the overhead of creating and maintaining each object individually is too high. The key idea behind the Flyweight […]

Facade Design Pattern: Streamlining Complexity in Code

What is facade design pattern?   The Facade Design Pattern is a structural design pattern that provides a simplified interface to a set of interfaces in a subsystem (a library, a framework, or any other complex set of classes), making it easier to use. It involves creating a facade class that represents a higher-level, unified […]

The Art of Decorating: Applying the Decorator Design Pattern in Real Life

As software developers, we all want to write code that is easy to maintain, scalable, and efficient. However, as software projects get increasingly complex, maintaining clean and efficient code becomes challenging. Here, the Decorator Design Pattern types comes into play. The Decorator Design Pattern is a structural pattern that allows adding new functionality to an existing […]

Composite Design Pattern – Simple or Complex? This is the question!

Composite is a structural design pattern that allows us to treat individual objects and compositions of objects uniformly. This pattern is especially useful when dealing with hierarchical structures, such as a tree of objects, where we need to work with individual objects as well as collections of objects in a consistent manner. How does the […]

Bridge Design Pattern – A different kind of Golden Gate

Structual design patterns – What is the bridge design pattern simplified? Bridge is part of Structural Design Patterns that decouples an abstraction from its implementation, allowing both to vary independently. What is the bridge design pattern used for? It is used to decouple the interface (the datatype) from its implementation, allowing them to be developed independently of one another, increasing […]

Adapter Design Pattern: Don't replace an old item, use an adapter instead

Adapter is a Structural Design Pattern that allows incompatible interfaces between classes to work together without modifying their source code. It acts as a bridge between two interfaces, making them compatible so that they can collaborate and interact seamlessly. This pattern is useful when integrating existing or third-party code into an application without modifying the […]

The Singleton Design Pattern

What is the purpose of singleton pattern? Singleton is a creational design pattern that ensures only a single instance of a class exists throughout an application and provides access to that instance from anywhere in the codebase. It is useful in situations where multiple instances of a class are undesirable or a single point of […]

Prototype Design Pattern – Don’t reinvent the wheel, start with a prototype

Prototype is a creational design pattern that lets us duplicate existing objects without having our code depend on their classes. For example, this pattern could be used to create multiple instances of the same object with unique attribute values such as color or size. Instead of creating a new class for each variation of an […]

Object Pool Design Pattern - Sharing is Caring

Object Pool is a software Creational Design Pattern that is utilized when instantiating a class is expensive in terms of time, computing resources, or both. Essentially, an Object Pool, also known as a Resource Pool, is a container that holds a limited number of objects for a short period of time. It provides a pool […]

Factory Method Design Pattern - Just a Little Builder

In object-oriented programming, the Factory Method is a Creational Design Pattern that allows us to create objects without specifying the exact class that will be instantiated. Instead of creating objects directly, we use a factory method to create and return them. This Design Pattern promotes code reuse and loose coupling between classes making our code […]

If It’s Complex, Let’s Call the Builder: Use and Applicability of the Builder Design Pattern

What is the Builder Creational Design Pattern and why do we need it? In real life, a builder constructs complex things and does this in small steps, piece by piece. In software development, the Builder Design Pattern allows us to handle the creation of different types and representations of a rather complex object by using […]

Abstract Factory Design Pattern Down to Earth

What is it all about? A design pattern is a generic, reusable solution to a commonly encountered problem within a specific context in software design. It is not a finished design that can be transformed directly into code. Instead, it is a description or template for how to solve a problem that can be used […]
