TIL java basically has roundabout (sorta) async now https://docs.oracle.com/en/java/javase/21/core/virtual-threads.html

i really haven't been keeping up with java changes since java 16 lol
Core Libraries
Virtual threads are lightweight threads that reduce the effort of writing, maintaining, and debugging high-throughput concurrent applications.

Whaat, a Java record component cannot be deprecated by Javadoc, only by annotation? That looks like a bug in javac to me, no? The JLS doesn't mention Javadoc explicitly: docs.oracle.com/javase/specs...

Thanks for the correction - the version of the Java docs I picked up to check on nanotime was an older (?much older?) version that was far less verbose; and since the result matched the epoch time I assumed that that was a deliberate choice.

基于日企的稳定性,的确是可以安心好好生活。但也同样基于日企的特性,有很多死板的地方。
我需要做的就是提升自己的业务能力,方便两年半后有更多的选择资本和底气。
无论新卒还是中途入社,都是在培训完基础Javase等就直接回到公司自学springboot开发的那一套,做完一个超简单的单体练手项目就分配到实际项目组打杂。我经常会在工作空余时间内争分夺秒去各种补必备的编程技能栈。因为内部培训制度的不合理性以及日企开发的冗余流程,之前被迫浪费了很多时间。

Hoje é simples. Só usar o Files. Mas em 2004 não era e todo javeiro com anos de experiência ficou dependente do google. 🤷‍♂️

Phaser is kind of a generalized CountDownLatch and it's apparently meant for implementing worker pools where the number of workers can change dynamically, or something.

Eu fico com raiva pela solução "correta" ser usar Reference.reachabilityFence, que é um método que não faz nada, só avisa pra JVM que o objeto ainda precisa ser mantido vivo. 😂

Definitely silly, and reason for it seems based around overflow issues while adding shorts together.

The term apparently is “binary numeric promotion” and there’s a list here for other cases too, not just for short.

You are wrong, I thought the people at intellij would knew a bit of java 😅. docs.oracle.com/javase/specs...

If the value p being boxed is ... int .. between -128 and 127 (inclusive), then let r1 and r2 be the results of any two boxing conversions of p. It is always the case that r1 == r2.
