Migrating applications from Java 11 to Java 17
The session outlines the agenda for exploring nine key developer features introduced between Java 11 and Java 17.
Applying data-oriented programming for concise java syntax
Fusing mathematical interfaces and matching engines separates concrete data structures from operational behaviors.
Overview of the Java features presentation
An introduction to syntax improvements and future releases in Java.
Interactive coding and evaluation using improved JShell
Using JShell for quick syntax experimentation and evaluating dynamic Java code.
Summarizing the capabilities of the modern Java scripting ecosystem
Recent ecosystem updates successfully remove traditional verbose limitations to make Java highly capable for fast automations.
Developing terminal user interfaces natively within Java scripts
Leveraging the Tambui framework enables rich graphical terminal interfaces directly programmed through declarative Java language constructs.
Evaluating static typing and performance benefits of Java scripts
Java offers significant benefits for scripting by providing static typing and a familiar development ecosystem.
Leveraging shebang support to run Java files directly
Adding a shebang directive allows seamless execution of single Java source files like native shell scripts.
Executing single-file Java source code without explicit compilation
Running Java source files directly through memory compilation eliminates the need for any separate compilation steps.
Jakarta EE 11 platform and Java API baseline
Aligning release cadences with Java LTS versions ensures the platform supports modern language features.
History of J2EE and enterprise Java beans
The historical complexity of J2EE explains the evolution toward streamlined modern enterprise Java frameworks.
Java level compilation requirements and runtime testing across generations
Application developers successfully adapt Java SE 17 execution safely because foundational toolchains freeze source code parameters at an earlier iteration.
Significant performance and language features launching in Java 21
Sequenced collections, virtual threads, and advanced switch pattern matching elevate performance and simplify expressive code logic.
The future of Java in modern web development
Assessing tools like Vaadin helps determine the feasibility of full-stack Java applications over complete JavaScript transitions.
Major language and productivity upgrades from Java 12 to 17
Enhancements across intermediate releases deliver helpful null pointer exceptions, text blocks, and record classes for immutability.
Productivity improvements and API updates in Java 11
Java 11 introduces a non-blocking HTTP client, single-file source code execution, and native TLS 1.3 support.
Risks of remaining on legacy Java versions
Production statistics highlight the dangers of missing bug patches and performance gains by staying on Java 8.
Strategic takeaways for continuous Java version migration
Consistently moving between long-term support versions ensures critical access to performance improvements and ongoing security patches.
Implementing data-oriented programming architectures in Java
Combining immutable generic structures with exhaustive logic drives application flow purely through deterministic types.
Using Java records as immutable lightweight data carriers
Defining immutable records reduces boilerplate code and prevents unintended data manipulation via reflection.
Simplifying concurrent code with Java 21 virtual threads
Java 21 virtual threads efficiently process high-volume concurrency without requiring developers to abandon imperative code.
Mechanics of virtual and carrier threads in Java
The Java Virtual Machine automatically unmounts blocked virtual threads to keep carrier threads freely available.
Learning Java features and design patterns interactively
Programmers can explore modern programming languages and architecture principles through customized dialogue and practical messaging examples.
Managing Java versions with Gradle toolchains
How toolchains resolve environment mismatches to ensure consistent and reproducible Java builds across teams.
Choosing Java over Python for enterprise AI ecosystems
Java offers better energy efficiency, stable dependency management, and robust enterprise integrations compared to Python.
Demonstrating code efficiency gains comparing standard Java and LangChain4j
A practical coding comparison highlights how LangChain4j eliminates excessive boilerplate for programmatic API interactions.

Optimizing native compilations in Java specifically tuned for lightweight Kubernetes deployments.
State of Java on AWS serverless applications
How managed Amazon Corretto distributions grant Java engineers stable long-term framework support.
Why Java lags in serverless adoption on AWS
Slow cold start times and high memory footprints hinder Java usage in AWS Lambda compared to Python and JavaScript.
Benchmarking untreated Java cold starts on Lambda
Stress testing a basic one-gigabyte Java Lambda shows excellent warm performance but critical three-second delays during cold initializations.
Optimizing Java startup processes for fast serverless workloads
Addressing traditional Java memory weight and slow warmup times using modern cloud-native frameworks.
Choosing Java 17 for modern Spring Boot applications
Why long-term support and improved syntax make Java 17 superior for new enterprise projects.
Introduction to Kotlin and Java interoperability
Overview of Kotlin's multi-paradigm nature and seamless integration with existing Java libraries.
