Design patterns are formalized best practices that the programmer can use to

solve common problems when designing an application or system.
|
||||
|

Design patterns can speed up the development process by providing tested, proven

||||
development paradigms.

|
||||
Reusing design patterns helps to prevent subtle issues that can cause major
|
||||
problems, and it also improves code readability for coders and architects who
|
||||
are familiar with the patterns.
|
||||
|
||||
# Getting started
|
||||
|
||||
This site showcases Java Design Patterns. The solutions have been developed by
|
||||
experienced programmers and architects from the open source community. The
|
||||
patterns can be browsed by their high level descriptions or by looking at their
|
||||
source code. The source code examples are well commented and can be thought as
|
||||
programming tutorials how to implement a specific pattern. We use the most
|
||||
popular battle-proven open source Java technologies.
|
||||
|
||||
Before you dive into the material, you should be familiar with various
|
||||
[Software Design Principles](https://java-design-patterns.com/principles/).
|
||||
Programming/Software Design Principles.
|
||||
|
||||
All designs should be as simple as possible. You should start with KISS, YAGNI,
|
||||
and Do The Simplest Thing That Could Possibly Work principles. Complexity and
|
||||
patterns should only be introduced when they are needed for practical
|
||||
extensibility.
|
||||
|
||||
Once you are familiar with these concepts you can start drilling down into the
|
||||
[available design patterns](https://java-design-patterns.com/patterns/) by any
|
||||
of the following approaches
|
||||
Once you are familiar with these concepts you can start drilling down into
|
||||
patterns by any of the following approaches
|
||||
|
||||
- Search for a specific pattern by name. Can't find one? Please report a new pattern [here](https://github.com/iluwatar/java-design-patterns/issues).
|
||||
- Using tags such as `Performance`, `Gang of Four` or `Data access`.
|
||||
- Using pattern categories, `Creational`, `Behavioral`, and others.
|
||||
|
||||
Hopefully you find the object oriented solutions presented on this site useful
|
||||
in your architectures and have as much fun learning them as we had developing them.
|
||||
- Using difficulty tags, `Difficulty-Beginner`, `Difficulty-Intermediate` & `Difficulty-Expert`.
|
||||
- Using pattern categories, `Creational`, `Behavioral` and others.
|
||||
- Search for a specific pattern. Can't find one? Please report a new pattern [here](https://github.com/iluwatar/java-design-patterns/issues).

@ -170,25 +169,24 @@ Use the Abstract Factory pattern when
|
||||
* you need a run-time value to construct a particular dependency
|
||||
* you want to decide which product to call from a family at runtime.
|
||||
* you need to supply one or more parameters only known at run-time before you can resolve a dependency.
|
||||
* when you need consistency among products
|
||||
* you don’t want to change existing code when adding new products or families of products to the program.
|
||||
|
||||
## Use Cases:
|
||||
|
||||
* Selecting to call the appropriate implementation of FileSystemAcmeService or DatabaseAcmeService or NetworkAcmeService at runtime.
|
||||
* Unit test case writing becomes much easier
|
||||
* UI tools for different OS
|
||||
|
||||
## Consequences:
|
||||
|
||||
* Dependency injection in java hides the service class dependencies that can lead to runtime errors that would have been caught at compile time.
|
||||
* While the pattern is great when creating predefined objects, adding the new ones might be challenging.
|
||||
* The code may become more complicated than it should be, since a lot of new interfaces and classes are introduced along with the pattern.

# Abstract Factory
|
||||

||||
|
||||
# Also known as
|
||||
|
||||
* Kit
|
||||
|
||||
---
|
||||
|
||||
# Intent
|
||||
|
||||
* Provide an interface for creating families of related or dependent objects without specifying their concrete classes
|
||||
|
||||
---
|
||||
|
||||
# Explanation
|
||||
|
||||
* [Wikipedia](https://en.wikipedia.org/wiki/Abstract_factory_pattern) says:
|
||||
> "The abstract factory pattern provides a way to encapsulate a group of individual factories that have a common theme without specifying their concrete classes"
|
||||
|
||||
<br />
|
||||
|
||||
* In plain words:
|
||||
* A factory that groups individual but related/dependent factories together without specifying their concrete classes;
|
||||
* A factory of factories;
|
||||
|
||||
---
|
||||
|
||||
# Example
|
||||
|
||||
* In a factory that creates kingdoms, we need objects with common theme:
|
||||
|
||||
* Elven kingdom needs an Elven king, Elven castle and Elven army;
|
||||
|
||||
* Orcish kingdom needs an Orcish king, Orcish castle and Orcish army;
|
||||
|
||||
<br />
|
||||
|
||||
* There is a dependency between the objects in the kingdom;
|
||||
|
||||
---
|
||||
|
||||
# Diagram
|
||||
|
||||
* Based on the kingdom example, the diagram below showcases the different concrete factories and their concrete products:

||||
|
||||

|
||||
* At runtime, we can define which Kingdom type is needed and pass it as a parameter to define which concrete KingdomFactory to instantiate;
|
||||
|
||||
* The concrete factory returned will then be able to produce the related objects of the specified type;
|
||||

|
||||
# Applicability
|
||||
|
||||
Use the Abstract Factory pattern when:
|
||||
|
||||
* A system should be independent of how its products are created, composed and represented;
|
||||
|
||||
* A system should be configured with one of multiple families of products;
|
||||
|
||||
* A family of related product objects is designed to be used together, and you need to enforce this constraint;
|
||||
|
||||
* You want to provide a class library of products, and you want to reveal just their interfaces, not their implementations;
|
||||
|
||||
---
|
||||
|
||||
# Applicability
|
||||
|
||||
Use the Abstract Factory pattern when:
|
||||
|
||||
* The lifetime of the dependency is conceptually shorter than the lifetime of the consumer;
|
||||
|
||||
* You need a run-time value to construct a particular dependency;
|
||||
|
||||
* You want to decide which product to call from a family at runtime;
|
||||
|
||||
* You need to supply one or more parameters only known at run-time before you can resolve a dependency;
|
||||
|
||||
---
|
||||
|
||||
#Use Cases
|
||||
|
||||
* Selecting to call the appropriate implementation of FileSystemAcmeService or DatabaseAcmeService or NetworkAcmeService at runtime;
|
||||
* Unit test case writing becomes much easier;
|
||||
|
||||
---
|
||||
|
||||
# Consequences
|
||||
|
||||
* Dependency injection in java hides the service class dependencies that can lead to runtime errors that would have been caught at compile time

## Intent
|
||||
Allow new functions to be added to existing class hierarchies without affecting those hierarchies, and without creating the troublesome dependency cycles that are inherent to the GOF VISITOR Pattern.
|
||||
|
||||
## Class diagram
|
||||
|
||||
|
||||
## Applicability
|
||||
This pattern can be used:
|
||||
|
||||
* When you need to add a new function to an existing hierarchy without the need to alter or affect that hierarchy.
|
||||
* When there are functions that operate upon a hierarchy, but which do not belong in the hierarchy itself. e.g. the ConfigureForDOS / ConfigureForUnix / ConfigureForX issue.
|
||||
* When you need to perform very different operations on an object depending upon its type.
|
||||
@ -25,18 +24,16 @@ This pattern can be used:
|
||||
|
||||
## Consequences
|
||||
The good:
|
||||
|
||||
* No dependency cycles between class hierarchies.
|
||||
* No need to recompile all the visitors if a new one is added.
|
||||
* Does not cause compilation failure in existing visitors if class hierarchy has a new member.
|
||||
|
||||
The bad:
|
||||
|
||||
* Violates the principle of least surprise or Liskov's Substitution principle by showing that it can accept all visitors but actually only being interested in particular visitors.
|
||||
* Parallel hierarchy of visitors has to be created for all members in visitable class hierarchy.
