[How Should Java Developers Build Front-Ends for Web, Mobile, and Desktop Today | Karsten Silz](https://meetupfeed.io/talk/how-should-java-developers-build-front-ends-for-web-mobile-and-desktop-today-by-karsten-silz)
Users access applications on PCs and mobile devices today. There are two obvious ways to build front-ends for these devices: Web applications and native applications. Cross-platform UI frameworks combine advantages from both approaches. Karsten will look at all these toolkits from the perspective of a Java developer and suggest which one to use in three common scenarios.

[Solving The Expression Problem | Richard Warburton & Raoul-Gabriel Urma](https://meetupfeed.io/talk/solving-the-expression-problem-using-modern-java-by-richard-warburton-raoul-gabriel-urma)
Java 9 to 17 has brought significant changes in how we can now write day to day Java code. In this talk, they will cover the notorious expression problem and how it can be addressed using Java’s most modern language features including switch expression, sealed classes and pattern matching. And what’s more, they’ll refactor a code written pre-Java 9, using new features and approaches whilst showing the resulting code benefits including cohesion, decoupling and readability.

[Faster Java Without Changing Any Code | Simon Ritter](https://meetupfeed.io/talk/faster-java-without-changing-any-code-by-simon-ritter)
Applications that run on the JVM benefit from a managed runtime environment with JIT compilation that can easily exceed the performance of natively compiled code. In this byte-sized session, Simon Ritter will look at some ways to improve the performance of your JVM-based applications without having to change a single line of code or even recompile!

[Let’s make Java fun to use | Max Rydahl Andersen](https://meetupfeed.io/talk/lets-make-java-fun-to-use-by-max-rydahl-andersen)
