IT討論區(200) - IT狗日夜鍛鍊去取勝

快，慳memory，冇GC spikes
但第一要錢買
第二冇咗JIT runtime optimization 理論上冇run in JVM 最大理論速度
第三compile 好撚耐
第四冇得用reflection

- record class != getter setter
- java switch expression只係implement左 c# pattern matching既一小部分
保守定大膽邊樣好係個人preference
C#確實比Java多breaking change, 不過講緊係極少數既情況先中到.
以我所知, 唔計你D identifier撞新keyword或者3rd party outdate既問題, 你拎幾十年前既code放係最新C# compiler度一樣compile到

GraalVM要錢?

C# lambda+async await+extension method+LINQ 一齊做嗰吓d API fluent到直情覺得有美感

Java成日話做到做到，但係佢就係冇咗呢d language features夾埋一齊聯合嘅效果

你Future Promise 係邏輯上係同async await一樣嘅嘢嚟，但async真係寫曲寫落手嘅時候真係順手好多，
所以對language design嚟講，係兩樣嘢

其實官方tooling掂, 冇乜人會想用community tooling

java 有咩阻止你寫getter setter?
另外睇唔到有咩係c# pattern matching 做到java 做唔到
不如你拎個example出嚟睇吓

language層面既getter setter唔係指自己寫個getXX(), setXX(). 係指呢種https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/using-properties

c# PM可以睇https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/functional/pattern-matching
例如Relational patterns果part應該冇c#底比較容易理解

IT post 日常
嘈language

手巴比女果圍

乜language都好請bug囝就好

We already have that in record class, what is your point?

c# PM可以睇https://learn.microsoft.com/en-us/dotnet/csharp/fundamentals/functional/pattern-matching
例如Relational patterns果part應該冇c#底比較容易理解

We also have that supported since JDK 19 (experimental) / JDK20 (preview feature)
you can take a look at this JEP https://bugs.openjdk.org/browse/JDK-8294285 to see what the JDK community is trying to achieve

交流吓啫

點解手巴自己唔知的

好熱鬧

好俾心機覆

想問有冇Ching熟「你無撚野下話」aka「港大工程撚」is who

有邊日唔開拖

Cc 力巴

sorry 我講漏咗
under openJdk 嘅graalvm 的確唔使錢
