jvm次要版本vs编译器次要版本 [英] jvm minor version vs compiler minor version

问题描述

当JVM运行用JDK编译的具有与JVM相同的主要版本但较高的次要版本的类时，JVM会抛出异常吗?

Will JVM throw exception when it runs classes compiled with a JDK that has same major version but higher minor version compared to JVM ?

推荐答案

JDK版本并不重要，

The JDK version does not really matter, the class file format version does. So far, the minor version of the class file format hasn't been used, and changes in the major version have always corresponded with major JDK release (counting 1.2 -> 1.3 -> 1.4 as major releases).

此外，javac的-target选项可用于生成与较早的运行时兼容的类文件.

Additionally, the -target option of javac can be used to produce class files compatible with older runtimes.
