VICTOR RENTEA - Functional Programming Patterns with Java8

Java 8 is cool... But do you know to write elegant code with it? Have strong coffee and come to this insane live-coding session to see some real-life functional programming patterns extracted from production code.

After leading 2 projects making heavy use of Lambdas and Streams, counseling many others at IBM, and teaching hundreds of developers at University and as an Independent Trainer, Victor will prove several best practices, patterns and anti-patterns he distilled over the years. All via a series of live coding exercises, like you've probably never saw in your life! You will hear about: Bloated Lambdas, A Happy Predicate, Stream Wrecks, How to Kill The Biggest Bug, Monads, Passing-a-block and The Loan Pattern, and 5 Ways to Implement Type-Specific Logic. Of course, as a Clean Code Maniac, Victor will always strive for maintainable, readable, elegant code. So you'll see a lot of refactoring.

PS: You know, some Joe will maintain your Java8 code at some point. So let's just hope Joe would be a nice safe guy...

45:35 I think it is more of a Visitor pattern than a Method Template, because it is a double dispatch.

in the end slides "Extract & @Override" - as I got it means Extends not Extract?

I don’t know what is the most surprising: me watching a 5 year old video or still seeing those same bad code in daily work when Java 21 is out🤔

Using Eclipse for historical reasons :D
