Integrity by Default - Inside Java Newscast #73#video#j_ms #performance #reflection
Integrity is a cornerstone of the Java Platform as it enables/bolsters reliability, maintainability, security, and performance, but there are operations that undermine it. Now, Java wants to lock them down by default.

Java and AI? - Inside Java Newscast #72#video#ai #java‑next #project‑valhalla #project‑babylon #project‑panama
AI development can be split into three categories: developing an ML model (where Java isn't competitive and is unlikely to become top of the class any time soon), developing an AI-centered product (where Java is well-positioned and will become stringer soon; but does this category matter in the long run?) and adding AI-based features to larger projects (where Java is already very good and will only become stronger thanks to Valhalla's value types, Panama's FFM and vector APIs, and Babylon's code reflection).

What Happened to Java's String Templates? Inside Java Newscast #71#video#project‑amber
JDK 23 doesn't contain the string template preview that was present in JDKs 21 and 22. Let's discuss why the feature was removed (probably not for the reasons you think), what a new proposal could look like, and when we may see it.

All Java 23 Features - Inside Java Newscast #70#video#java‑23
Java 23 will be released on September 17th but it's branched today (June 6th 2024) and so its feature set is final. Generational ZGC, Markdown in JavaDoc, deprecations in Unsafe, the removal of string template, and the thoughtful evolution of eight preview features. Let's take a closer look!

Module Imports in Java 23 - Inside Java Newscast #69#video#java‑23 #j_ms
To reduce the overhead of using APIs, particularly in single source files, Java 23 previews module import declarations of the form import module $moduleName, which import all packages exported by the named module

Java 23: Restoring the Balance with Primitive Patterns - Inside Java Newscast #66#video#java‑23 #pattern‑matching

Does Java 22 Kill Build Tools? - Inside Java Newscast #63#video#java‑22 #on‑ramp
Java 22 brings multi source-file execution to the platform. It allows us to run programs consisting of multiple source files and even dependencies with just a simple java command. For experienced developers, this will make exploration and experimentation simpler but it's a real game changer for people just learning Java or even just to program: They can now write Java code from single to multiple source files and even add dependencies before they need to consider an IDE or build tool.

Java 22 Previews Statements Before super(...) and this(...) - Inside Java Newscast #62#video#java‑22 #project‑amber
Whether for validation, preparation, or splitting and sharing arguments, it can be quite annoying that Java doesn't allow statements before the super(...) or this(...) call in a constructor. Luckily Java 22 is about to change that with JEP 447, which previews statements before the explicit constructor invocation.

How Project Valhalla And JSpecify Can Kill NPEs#video#project‑valhalla #libraries #conversation
Project Valhalla's value types need to be aware of which instance can be null and which can't, so the JVM can inline them. So will Java get a null-aware type system after all? Not quite, but it may get close and JSpecify can help with some of those steps.

JDK 22 will be released on March 19th 2024 but it's forked today (Dec 7th 2023) and so its feature set is final. Unnamed patterns and variables, the FFM API, and multi-source-file programs are the highlights but there is so much more. Let's unpack!

Upgrading From Java 17 To 21: All You Need To Know#video#java‑21 #migration
Java 21 is chock-full of great features but that's for naught of you can't actually upgrade, so I've collected all potential upgrade hurdles and we'll go over every issue that you may encounter on the road from Java 17 to 21

Java 21 is no LTS Version - Inside Java Newscast #52#video#java‑21
Let's separate Java from JDK, OpenJDK from its vendors, and maintenance from support, so we better understand how the ecosystem functions and what long-term support really means.

Java 21 - The Other Side - Inside Java Newscast #51#video#java‑21
OMG, how is there even more in JDK 21?! Scoped values preview, key encapsulation mechanism API, a new JFR command, and various API improvements. Generational Shenandoah is out, though, and it doesn't look good for the 32-bit Windows port either.
Image with slug inside-java-newscast-50
All That is in Java 21?! 😱 - Inside Java Newscast #50#video#java‑21
JDK 21 is almost too good to be true: It finalizes virtual threads, sequenced collections, generational ZGC, and the pattern matching basics; and evolves and introduces over half a dozen other features.

Getting Rid Of Unused Variables (Finally) - Inside Java Newscast #46#video#pattern‑matching

New (Sequenced) Collections In Java 21 - Inside Java Newscast #45#video#collections #java‑21
All lists, some sets, and some maps have an encounter order, but the collections framework has no type to capture this property and define operations like getting or removing first and last elements or iterating in reverse order. Sequenced collections will fix that in Java 21.

The Holy Grail of Java Performance - Inside Java Newscast #43#video#project‑leyden
The goal of Project Leyden is to improve the startup time, time to peak performance, and footprint of Java programs.

Data-Oriented Programming - Inside Java Newscast #29#video#records #sealed #pattern‑matching #patterns #techniques
Data-oriented programming focuses on modeling data as data (instead of as objects). Records for data and sealed types for alternatives let us model immutable data where illegal states are unrepresentable. Combined with pattern matching we get a safe, powerful, and maintainable approach to ad-hoc polymorphism that lets us define operations on the data without overloading it with functionality.
