Java 24 也是一个过渡版本, 还是到下面两个链接中找相应的更新
IntelliJ IDEA 对 Java 24 Language level 描述是
- 24 - No new language features
- 24 (Preview) - Flexible constructor bodies, simple source files, etc.
把上面第二个链接中的特性列出来
- 404: Generational Shenandoah (Experimental)
- 450: Compact Object Headers (Experimental)
- 472: Prepare to Restrict the Use of JNI
- 475: Late Barrier Expansion for G1
- 478: Key Derivation Function API (Preview)
- 479: Remove the Windows 32-bit x86 Port
- 483: Ahead-of-Time Class Loading & Linking
- 484: Class-File API *
- 485: Stream Gatherers *
- 486: Permanently Disable the Security Manager
- 487: Scoped Values (Fourth Preview)
- 488: Primitive Types in Patterns, instanceof, and switch (Second Preview)
- 489: Vector API (Ninth Incubator)
- 490: ZGC: Remove the Non-Generational Mode
- 491: Synchronize Virtual Threads without Pinning
- 492: Flexible Constructor Bodies (Third Preview)
- 493: Linking Run-Time Images without JMODs
- 494: Module Import Declarations (Second Preview)

- 498: Warn upon Use of Memory-Access Methods in sun.misc.Unsafe
- 499: Structured Concurrency (Fourth Preview)
- 501: Deprecate the 32-bit x86 Port for Removal
Java 24 中列出的特性恰如其版本一样，有 24 条，因其是一个过渡版本，多数为非正式特性，也就为什么 IntelliJ IDEA 从语言特性上把 Java 标记为 No new language features. 其实也不然，个人觉得有两个正式特性值得关注，即 Class-File API 和 Stream Gathers。
