Welcome to HappyCoders

Hello John Doe,

Sven here – great to have you on board. Here's what matters most:

What to Expect

Once a month, I'll send you the HappyCoders newsletter on modern Java: new versions & features, performance, and JVM insights. One email a month – that's it.

Two Gifts to Get You Started

Both HappyCoders cheat sheets were already available for download on the thank-you page. In case you skipped them there: here they are again – so you'll always have the links in your inbox:

👉 Java Versions Cheat Sheet – all features of the latest Java versions at a glance

👉 Big O Cheat Sheet – the complexities of the most important algorithms and data structures

One Quick Question

So I know where I can help you most: What are you struggling with most in Java right now?

Just reply directly to this email – one sentence is enough. I read every answer.

Happy Coding!
Sven

P.S.: One click is all it takes: What brought you to HappyCoders?

I want to bring my own Java up to date · I want to get my team moving to a newer Java · I decide on training and technology for a team · Studies, apprenticeship, exam, or job interview · I teach or pass on knowledge

Something else? Just reply in one sentence.
