Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.
But these can also be overused and fall into some common pitfalls.
To get a better understanding on how Streams work and how to combine them with other language features, check out our guide to Java Streams:

Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

Refactor Java code safely — and automatically — with OpenRewrite.
Refactoring big codebases by hand is slow, risky, and easy to put off. That’s where OpenRewrite comes in. The open-source framework for large-scale, automated code transformations helps teams modernize safely and consistently.
Each month, the creators and maintainers of OpenRewrite at Moderne run live, hands-on training sessions — one for newcomers and one for experienced users. You’ll see how recipes work, how to apply them across projects, and how to modernize code with confidence.
Join the next session, bring your questions, and learn how to automate the kind of work that usually eats your sprint time.

Building a full-fledged, production-ready registration for your web application is oh so much more than just putting together a simple registration page.
There are a lot of questions that need to be answered:
- How do I verify the email addresses of new users?
- How do I properly and safely store user credentials?
- What if a user forgets their password?
- What about users changing their own password?
- How strong should passwords be? How can I enforce some sensible defaults in the app so that my users have good, strong passwords?
- What if I have more than one type of user? I need a good way to store roles and privileges.
- What about security questions? Should I even have them?
- How do I do all of this with good localization support? There are a lot of messages involved.
In this series, we’ll go over the full registration process with Spring Security. The source code for these tutorials is available over on GitHub.
