Adapter Pattern

The Adapter pattern is a structural design pattern that allows incompatible interfaces to work together by creating a bridge between them. It involves creating an adapter class that wraps an existing class and provides a compatible interface that other classes can use. This pattern is useful when you need to reuse existing classes that have different interfaces, or when you need to integrate third-party libraries into your application that have incompatible interfaces....

Singleton Pattern

The Singleton pattern is a creational design pattern that ensures that a class has only one instance and provides a global point of access to that instance. This pattern is useful when you need to limit the number of instances of a class to one, and when you want to provide a single point of access to that instance throughout your application. Example Here’s an example of how to implement the Singleton pattern in Python:...

Prototype Pattern

Design patterns in software engineering are reusable solutions to common problems that arise in software development. One such design pattern is the Prototype Design Pattern, which is used to create new objects by cloning existing objects. In this article, we will explore what the Prototype Design Pattern is, when to use it, examples, pros and cons, and related design patterns. What is the Prototype Design Pattern The Prototype Design Pattern is a creational design pattern that allows the creation of new objects by copying existing objects....

Builder Pattern

The Builder pattern is a creational design pattern that separates the construction of complex objects from their representation. It provides a step-by-step approach to building objects, allowing you to create different variations of an object while keeping the construction process consistent. Example Here’s an example of the Builder pattern implemented in Python: class Product: def __init__(self): self.part_a = None self.part_b = None def __str__(self): return f"Part A: {self.part_a}, Part B: {self....

Abstract Factory Pattern

The Abstract Factory pattern is a creational design pattern that provides an interface for creating families of related or dependent objects, without specifying their concrete classes. In this pattern, there is an abstract factory class that defines a set of abstract methods for creating related or dependent objects. Each concrete factory class that implements the abstract factory class provides its own implementation of these abstract methods, which creates specific families of related objects....
