Design Patterns in Scala

Welcome to Design Patterns implemented using Scala programming language. Each design pattern is explained with a problem statement, solution, steps to implement, implementation (source code), and when to use.

Design patterns are typical solutions to common problems in software design. Each pattern is a blueprint that can be customized to solve a particular design challenge in various situations. They provide a shared language and framework for expressing solutions and discussing design alternatives.

The Gang of Four classifies design patterns into three distinct categories: Creational, Structural, and Behavioral.

1. Creational Patterns

These patterns deal with object creation mechanisms, ensuring that objects are created in a manner suitable to the situation. 

Singleton Design Pattern in Scala
Factory Method Design Pattern in Scala
Abstract Factory Design Pattern in Scala
Builder Design Pattern in Scala
Prototype Design Pattern in Scala

2. Structural Patterns 

Structural patterns are all about ensuring different pieces of a system fit together well. They help ensure that when one part of a system changes, the entire structure of the system doesn't need to change.

3. Behavioral Patterns 

Behavioral patterns deal with communication between objects, how they operate, and the responsibilities among them.
