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 2023 06 22 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 2023 06 08 script java easily in 21 and beyond inside java newscast 49 video java basics on ramp to give java and programming beginners a better learning path jep 445 proposes to allow stand alone main methods that are non public non static and don t have an args array and we re also jep draft for multi file programs 2023 05 25 scaling simply with virtual threads talk project loom java 21 virtual threads combine the simplicity of blocking code with the resource efficiency and scalability of reactive programming and in this talk you re going to learn how they do that and how you can use them in your project 2023 05 24 save 10 20 memory with compact headers inside java newscast 48 video performance jdk enhancement proposal 450 proposes to merge a compressed class word into the mark word to reduce object header size on 64 but systems from 96 128 bits to 64 bits thus saving 10 20 of heap space 2023 05 11 getting rid of unused variables finally inside java newscast 46 video pattern matching jep 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 13 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 2023 03 30 java 20 post java 20 the list of big new features that can be used in production with java 20 is rather short that was it already pretty boring these six month releases we really don t need to take a closer look 2023 03 14 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 project lead mark reinhold recently proposed to extend the java programming model with features for selectively shifting and constraining computation with condensors let s look at his white paper and roadmap 2023 03 02 prepare your code bases for future java inside java newscast 41 video deprecation tools what do the security manager applet api finalization and primitive wrapper constructors have in common what about cms nashorn rmi activation and biased locking and what does jdeprscan have to do with all of this 2023 02 02 java s plans for 2023 inside java newscast 40 video project amber project galahad project leyden project lilliput project loom project panama project valhalla a summary of what happened in 2022 and what will probably happen in 2023 for projects amber galahad leyden lilliput loom panama and valhalla 2023 01 19 24 java features you missed in 2022 inside java newscast 39 video collections documentation java 18 java 19 pattern matching performance records structured concurrency jdk 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 15 from idea to ide how java features are considered designed and shipped talk openjdk community how a community of java enthusiasts drives innovation for 15 years turning ideas into designs into code into features you can use in your ide 2022 11 13 graalvm in openjdk and more javaone announcements inside java newscast 36 video community java 8 java 17 openjdk performance oracle will contribute graalvm s just in time compiler

at java s persistent pain points this talk discusses released previewing and upcoming features achieve that and make java more expressive more succinct and more readable 2022 09 30 data oriented programming version 1 1 talk dop pattern matching project amber data 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 27 loom in the java ecosystem inside java newscast 34 video java 19 project loom libraries among other things java 19 ships with virtual threads structured concurrency apis sealed types and pattern matching in switch all of them as previews but still very cool i m using these features here to create a github crawler 2022 09 27 java 19 in action inside java newscast 33 video java 19 dop project loom among other things java 19 ships with virtual threads structured concurrency apis sealed types and pattern

video collections lambda sequenced collections introduce an abstraction for collections with a known encounter order like all lists and some sets and maps it will be easy to add get or remove the first and last elements and to iterate or stream in reverse order we re also discussing immutable collections and pure functions more on all of this at javaone 2022 08 11 java q a inside java newscast 30 video project leyden project lilliput project valhalla project amber we asked you for questions on youtube reddit and twitter and are here to answer a bunch of them from projects amber to valhalla leyden to lilliput from language to performance from the immediate future to pipe dreams we covered a lot of ground 2022 07 28 data oriented programming inside java newscast 29 video records dop 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 2022 07 14 what is openjdk inside java newscast 28 video openjdk community java basics what s openjdk or the openjdk how does it work and what does it do here s the
