The LJC is an official Java User Group for developers based in London. It was founded in November 2007 and since then has grown to over 5000 members and is now the biggest Java User Group in the UK.
What goes on in the LJC?
We run a variety of regular events ranging from social events and technical presentations to our full day unconference. On top of the events we run prize draws and have an active mailing list/forum. We support the Graduate Development Community in London and promote London based Open Source Software projects where possible.
Who can join?
Membership is restricted to Java developers working in or around London (or those hoping to train in Java, or relocate to London). Membership will not be granted to those involved in the recruitment industry.
Is there a fee to Join, is there a fee for the events?

About this event
The LJC is delighted to continue our new series of events, aimed at giving all Community members an opportunity to present at an LJC meet-up.
If you have an interesting topic to share, these events are for you. You don’t have to be an experienced speaker - we want to hear your story and offer you a friendly, informal platform to practise and improve your presentations.
For attendees we want this to be a meeting place, where you can talk and network with other technologists in London.
If you’d like to speak at a future event, please submit your talk and bio details here: https://sessionize.com/ljc/
Huge thanks to our friends at Metro Bank for hosting this event and supporting our Community.
Speaker One: Simon Copsey
Title:
From Diapers to Delivery: Parenting Lessons for Effective Management
Synopsis:
Parenthood often arrives with little time for preparation. Our idea of 'good' parenting usually involves emulating what we’ve observed in others, whilst hoping we won't do any permanent damage our kids.Stepping into a managerial role can feel remarkably similar: we often have to rely on mimicking behaviours we’ve seen in others, despite knowing this may be imperfect or uncomfortable.Fortunately, there is a science to becoming a better manager, and we can draw inspiration from our experiences as parents (or children).In this talk I hope to provide you with a systematic method for improving your approach to management, so you can get closer to being the manager you most want to be.Speaker Two: Marcin Kruglik
Title:
Jakarta EE 101
Synopsis:
Jakarta EE still carries a lot of baggage from its Java EE days — that it’s outdated, not responsive, and no longer relevant because "everyone has moved to Spring." But are these opinions actually based on facts and a real understanding of the project?In this talk, we’ll explore what Jakarta EE really is — and probably more importantly, what it’s not.
Is it a competitor to Spring? Is it still relevant today? What’s its relationship with MicroProfile? How many of us are actually using Jakarta EE in our projects?
And finally, is there anything new happening in Jakarta EE?This event is organised by RecWorks on behalf of the London Java Community.

Speaker One:
Simon Ritter - Deputy CTO at Azul Systems
Talk: Java Patterns: Usage and PuzzlesThe goal of project Amber within OpenJDK is to explore the inclusion of smaller, productivity-oriented Java language features. One part of this that has delivered new functionality in recent versions is pattern matching.
Pattern matching combines application code logic to test if an expression has a specific type or structure and extract components of its state for processing.
Pattern matching is now well embedded in the Java language using the following features, defined by JDK Enhancement Proposals (JEPs)
• Pattern matching for instanceof (JEP 433)
• Pattern matching for switch (JEP 441)
• Record patterns (JEP 440)
• Unnamed patterns and variables (JEP 456)
• Primitive types in patterns, instanceof and switch (JEP 455)In this session, we’ll look at the details of these new language features and a more general look at pattern matching.
We’ll also have some fun with several Pattern Puzzlers that show how you need to be careful with some edge cases.
The session will hopefully both be informative and fun!

David Cooke, Developer at LMAX
Talk: Lock, Stock and a Smoking SynchronizedJVM offers a number of ways to implement "mutual exclusion" in multithreaded applications. We will take a deep long stare at synchronized. Very convenient, but at a price - also known as "just an implementation detail". You will learn how this works, what's behind, what's behind the behind, why it matters, what makes "better alternatives" actually better.
What is "adaptive locking"?
What do threads do when they are parked? If you ever wondered, this talk is for you.
You will not leave deflated, unlike an ObjectMonitor.Speakers two bios:
David is interested in all things low latency Java. At LMAX he works on the SRE team, tackling microsecond level challenges on a complex code base.This event is organised by RecWorks on behalf of the London Java Community.
