Here's how primitive patterns (in Java 23) and other patterns (in future versions) will fix that.2024-04-04(Dirty?) Tricks in Java 22 - Inside Java Newscast #64#video#pattern‑matching #optional #clean‑codePattern matching Optional, expanding sealed type hierarchies, nesting switches, reverting instanceof, and more - so many (dirty) tricks to play around with in modern Java2024-02-29The Hottest Language You Didn't Have On Your Radar#talk#pattern‑matching #performance #records #virtual‑threadsWith so much going on in the programming language space, it's easy to miss any specific language's success story and so in this talk I want to put a particularly hot one on your radar2024-02-05Java 21 Pattern Matching Tutorial#video#java‑21 #pattern‑matching #java‑basicsJava 21 is the first Java release with all essential pattern matching features finalized: sealed types, type patterns, an improved switch, records, and record patterns. This tutorial puts them all together.2023-09-17Modern Java in Action#talk#java‑21 #virtual‑threads #pattern‑matching #recordsLet's write a GitHub Crawler and let's throw in everything Java (23) has to offer2023-09-03Getting Rid Of Unused Variables (Finally) - Inside Java Newscast #46#video#pattern‑matchingJEP 443 proposes to add unnamed variables and patterns to Java. With them, unused variables and patterns can be replaced by a single underscore, which helps writing readable and maintainable code.2023-04-1324 Java Features You Missed In 2022 - Inside Java Newscast #39#video#collections #documentation #java‑18 #java‑19 #pattern‑matching #performance #recordsJDK 18 and JDK 19 preview a number of big ticket features but they also come with a lot of smaller improvements. Here are 24 less-known features that were added to Java in 2022. Among them additions to Future and ForkJoinPool, to HashSet and HashMap, Security and GC improvements, Custom Localized Date-Time Formats and an Internet Address Resolution SPI, and much more.2022-12-15Data-Oriented Programming - Version 1.1#talk#pattern‑matching #sealed #project‑amberData-oriented programming models data as data: records for entities and sealed types for alternatives. Combined with pattern matching we can define operations on the data without overloading it with functionality.2022-09-27Data-Oriented Programming - Inside Java Newscast #29#video#records #sealed #pattern‑matching #patterns #techniquesData-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.2022-07-14Deconstructing Records in Pattern Matching - Inside Java Newscast #26#video#project‑amber #pattern‑matchingHow record patterns use records' transparency to safely deconstruct them in pattern matching, allowing us to separate checking structure and value of data from processing it.2022-06-02News Grab Bag: Loom Virtual Threads, Lilliput, Pattern Matching, ... - Inside Java Newscast #25#video#project‑loom #tools #project‑lilliput #project‑amber #pattern‑matching #communityProject Loom's virtual threads are merged and ship with JDK 19 - here's to prepare for them.

Guarded patterns, which belonged to patterns, are replaced with when clauses, which belong to the case. 2. null needs to be handled by a specific case null.2022-05-05How To Use switch In Modern Java#post#switch #pattern‑matchingSince Java 14 introduced switch expressions, using switch isn't as straight-forward as it used to be: colons or arrows, statement or expression, labels or patterns?
