The facade pattern doesn’t force us to unwanted tradeoffs, because it only adds additional layers of abstraction. Sometimes the pattern can be overused in simple scenarios, which will lead to redundant implementations. 5. Conclusion In this article, we’ve explained the facade pattern and demonstr...
In this tutorial, we’ll review an interesting pattern that is not a part of classicalGoFpatterns – the Pipeline pattern. It’s powerful and can help resolve tricky problems and improve an application’s design. Also, Java has some built-in solutions to help implement this pattern; we’ll ...
Composite Design Pattern in Java--转 https://dzone.com/articles/composite-design-pattern-in-java-1 The composite pattern is meant to "compose objects into a tree structure to represent part-whole hierarchies. Composite lets clients treat individual objects and compositions of objects uniformly" Comp...
Iterator design patternTake traversal-of-a-collection functionality out of the collection and promote it to "full object status". This simplifies the collection, allows many traversals to be active simultaneously, and decouples collection algorithms from collection data structures. Design...
Facade. This article describes the Facade Design Pattern and its usage in the programming language Java. 1. Facade Pattern 1.1. Definition The Facade Pattern provides a unified interface to a set of interfaces within a subsystem. By defining a higher-level interface, the Facade Pattern ...
Design pattern in Java SE and Java EE APIs You can find an overview of a lot of design patterns in Wikipedia. It also mentions which patterns are mentioned by GoF. I'll sum them up here and try to assign as many pattern implementations as possible, found in both the Java SE and Java...

Note:Learn more about theFactory Design Pattern. 3. Abstract Factory Pattern The abstract factory pattern is similar to the factory pattern and is a factory of factories. If you are familiar with the factory design pattern in Java, you will notice that we have a single factory class that ret...
