在模块级别的build.gradle文件中,找到javaCompilerVersion属性,将其值从”17.0.6”修改为”1.8”。这样就可以确保该模块使用的Java版本也是Java 8。示例代码如下:// module-level build.gradle文件中的相关代码android {compileOptions {sourceCompatibility JavaVersion.VERSION_1_8targetCompatibility JavaVersion.VERSION_1...
首先,需要明确你的应用程序或库是否需要兼容Java 8。这通常取决于你的目标用户群体和他们的运行环境。 如果确实需要兼容Java 8,那么你需要确保所有使用的库和工具链都支持Java 8。 检查现有代码库中是否使用了Java 8不兼容的特性或API: 在Java 8之后,Java引入了许多新特性,如Lambda表达式、流(Streams)API等。如果...
以下是如何从Java 8迁移到Java 17的代码示例。 Java 8 代码: importjava.util.Arrays;importjava.util.List;publicclassUserApp{publicstaticvoidmain(String[]args){List<String>users=Arrays.asList("Alice","Bob","Charlie");users.stream().filter(user->user.startsWith("A")).forEach(System.out::print...
在吞吐量方面,Parallel 中 JDK 8 和 JDK 11 差距不大,JDK 17 相较 JDK 8 提升 15% 左右;G1 中 JDK 17 比 JDK 8 提升 18%;ZGC 在 JDK 11[2]引入,JDK 17 对比JDK 11 提升超过 20%。 延迟比较 在GC 延迟方面,JDK 17 的提升更为明显。我们可以看到为缩短 GC 暂停时间所做的努力都得到了回报,很...

SPI(Service Provider Interface),是JDK内置的一种服务提供发现机制,可以用来启用框架扩展和替换组件,主要是被框架的开发人员使用,比如java.sql.Driver接口,其他不同厂商可以针对同一接口做出不同的实现,MySQL和PostgreSQL都有不同的实现提供给用户,而Java的SPI机制可以为某个接口寻找服务实现。Java中SPI机制主要思想是将...
