Java 9 到 Java 25：语言演进与技术革新分析

1.模块化系统与工程革新（Java 9）

核心特性：JPMS（Java Platform Module System）
- 引入模块化概念，解决「JAR 地狱」问题
- 示例：声明模块依赖
```
module com.example.app { requires java.sql; exports com.example.utils; }
```
JShell REPL 工具：交互式编程环境
性能优化：G1 垃圾回收器成为默认收集器

2.语法糖与生产力提升（Java 10-15）

局部变量类型推断（Java 10）

var list = new ArrayList<String>(); // 自动推断类型

文本块（Java 15）

String json = """ { "name": "Java", "version": 25 }""";

Record 类（Java 14）
简化不可变数据载体：
```
record Point(int x, int y) { }
```

3.并发与性能突破（Java 16-21）

ZGC 与 Shenandoah 垃圾回收器
- 亚毫秒级暂停（目标 <1ms）
- 支持 TB 级堆内存

虚拟线程（Java 21）

try (var executor = Executors.newVirtualThreadPerTaskExecutor()) { executor.submit(() -> processRequest()); // 轻量级线程 }

向量 API（Java 16 孵化，Java 17 预览）
利用 SIMD 指令加速计算：

var a = FloatVector.fromArray(SPECIES, array, 0); var b = FloatVector.fromArray(SPECIES, array, offset); var c = a.mul(b).add(c);

4.未来方向（Java 22-25）

值类型（Valhalla 项目）
减少对象开销，提升内存效率：
```
inline class Money { double amount; Currency currency; }
```
