Design patterns

 Design patterns provide a standard terminology and are specific to particular scenarios and problems. Design patterns are not finished code but templates or blueprints only.

Key Characteristics of Design Patterns

  • Reusability: Patterns can be applied to different projects and problems, saving time and effort in solving similar issues.
  • Standardization: They provide a shared language and understanding among developers, helping in communication and collaboration.
  • Efficiency: By using these popular patterns, developers can avoid finding the solution to same recurring problems, which leads to faster development.
  • Flexibility: Patterns are abstract solutions/templates that can be adapted to fit various scenarios and requirements.

Types of Software Design Patterns

There are three types of Design Patterns:

  • Creational Design Pattern
  • Structural Design Pattern
  • Behavioral Design Pattern

Creational Design Patterns focus on the process of object creation or problems related to object creation. They help in making a system independent of how its objects are created, composed and represented.

Structural Design Patterns solves problems related to how classes and objects are composed/assembled to form larger structures which are efficient and flexible in nature. Structural class patterns use inheritance to compose interfaces or implementations.

3. Behavioral Design Patterns

Behavioral Patterns are concerned with algorithms and the assignment of responsibilities between objects. Behavioral patterns describe not just patterns of objects or classes but also the patterns of communication between them. These patterns characterize complex control flow that’s difficult to follow at run-time.

Archunit test

  ArchUnit  integrates nicely with the  JUnit  test framework, and so, they are typically used together.  All we have to do is add the  archunit-junit 5  dependency to match our  JUnit  version: < dependency > < groupId > com.tngtech.archunit </ groupId > < artifactId > archunit-junit5 </ artifactId > < version > 0.14.1 </ version > < scope > test </ scope > </ dependency > Step 1: The first step is to create a set of Java classes that will be checked for rules violations . We do this by instantiating the  ClassFileImporter  class and then using one of its  importXXX()  methods: JavaClasses jc = new ClassFileImporter () .importPackages( "com.baeldung.archunit.smurfs" ); Step 2:  Let’s try to implement the first rule defined above using this API. We’ll use the  classes()  method as our anchor and add additional constraints ...

Hexagonal Architecture

Image
  Hexagonal architecture is a model of  designing software applications around domain logic  to isolate it from external factors. The domain logic is specified in a business core, which we’ll call the inside part, with the rest being outside parts.  Access to domain logic from the outside is available through  ports  and  adapters .  here we divide our application into three layers:  application (outside), domain (inside), and infrastructure (outside): Through  the application layer, the user or any other program interacts  with the application. This area should contain things like user interfaces, RESTful controllers, and JSON serialization libraries. It includes anything  that exposes entry to our application, and orchestrates the execution of domain logic. In the domain layer, we keep the code that touches and implements business logic . This is the core of our application. This layer should be isolated from both the applica...

visitor design pattern

Image
  The Visitor design pattern is a  behavioral pattern  that allows you to add new operations to a group of related classes without modifying their structures. Real-World Example of Visitor Design Pattern A simple example of the Visitor design pattern is in an online shopping cart. Imagine you have different items like books, electronics, and clothing. Each item can accept a visitor that performs actions like calculating the total price or applying discounts. This way, you can add new features without changing the item classes, making the system easier to maintain and update. UML Class Diagram of Visitor design pattern Components of Visitor Design Pattern The Visitor design pattern consists of several key components that work together to enable its functionality. Here’s a breakdown of these components: Visitor Interface : This interface declares a visit method for each type of element in the object structure. Each method is designed to handle a specific element type. Concr...
