Details:
Exciting things are happening for CJUG this February!! CJUG will again be collaborating with the Chicago Kotlin Users Group (thank you CKUG!!). In addition to hosting the amazing Daniel Hinojosa (an active speaker for the highly acclaimed No Fluff Just Stuff series of conferences), we are also starting to collaborate with the highly acclaimed Virtual Java Users Group extending our reach to the 18,000+ audiences from all over the world!
Java Design Patterns Revisited through a Functional Lens
Since 1994, the original Gang of Four Design Patterns book, "Design Patterns: Elements of Reusable Object-Oriented Software" has helped developers recognize common patterns in development. The book was originally written in C++, but there have been books that translate the original design patterns into their preferred language. One feature of "The Gang of Four Design Patterns" that has particularly stuck with me has been testability for the most part. With the exception of singleton, all patterns are unit-testable. Design Patterns are also our common developer language. When a developer says, "Let's use the Decorator Pattern," we know what is meant.
What's new, though, is functional programming, so we will also discuss how these patterns change in our new modern functional programming world. For example, functional currying in place of the builder pattern, using an enum for a singleton, and reconstructing the state pattern using sealed interfaces. We will cover so much more, and I think you will be excited about this topic and putting it into practice on your codebase.
