Das nächste grosse Ding in Java

SPEAKER: Falk Sippach   COMPANY: embarc Software Consulting GmbH

KEYWORDS: Language, Architecture, Concept

Einer der grossen Pluspunkte von Java war und ist das statische, starke Typsystem. Das hilft Millionen von Entwicklern, viele Fehler bereits zur Compilezeit zu entdecken und macht die Entwicklung robuster sowie effizienter. Allerdings schleppt Java mit der Unterscheidung zwischen primitiven und Referenztypen von Beginn an eine schwere Bürde mit sich. Die vor etwa 30 Jahren aus Performancegründen eingeführten primitiven Datentypen integrieren sich nicht gut mit modernen Ansätze wie Generics, Stream API oder Pattern Matching.

Back to Basics: Crafting Quality Software in the Age of Complexity

SPEAKER: Scott Gerring   COMPANY: Datadog

KEYWORDS: Lessons learned, Performance, Technology, Tools

In the age of microservices, developers often find themselves drowning in incidental complexity – making countless decisions about queues, serverless technologies, databases, Kubernetes clusters, and much more. This complexity can overshadow the foundational task of writing clear, maintainable, and robust code.

I Didn't Know You Could Do That With Java Streams!?

SPEAKER: François Martin   COMPANY: Karakun

KEYWORDS: Lessons learned, Technology, Tools

Over years of working with many Java codebases, I see the same mistakes being made over and over again when it comes to using Streams. Most Java developers are familiar with the basics, but many do not know about advanced features that could make their code easier to read and perform better at the same time. In this talk, I will share the common problems I faced and how I used advanced Stream techniques and Collectors to improve those codebases.

Implementierung von DDD leicht gemacht mit Spring und jMolecules

SPEAKER: Stefan Heinzer   COMPANY: ELCA Informatik AG

KEYWORDS: Architecture, Concept, Technology, Tools

Das Versprechen des Domain-Driven Designs (DDD), "Komplexität im Herzen der Software zu beherrschen“, ist sehr reizvoll. In der Praxis übernehmen jedoch viele Projekte nur ausgewählte Konzepte und Techniken. Besonders bei der Umsetzung in Code fallen Entwickler oft in traditionelle Muster wie datenzentriertes Design oder „Smart UI“ zurück, bei denen die Domänenlogik über alle Schichten des Codes verteilt ist – auf eine Weise, die schwer oder gar nicht mehr kontrollierbar ist.
