JRE包含在JDK与独立JRE之间 [英] JRE included with JDK vs. standalone JRE

问题描述

JDK（位于jre文件夹内）的JRE与独立的JRE之间有什么区别？有没有？

What's the difference between the JRE included with the JDK (located inside of the jre folder) and the standalone JRE? Is there any?

推荐答案

独立JRE（有时也称为公共JRE）通常不包含HotSpot的服务器版本。它还缺少JDK（JavaDB，javac，tools.jar等）中包含的工具。

The "standalone JRE" (sometimes also referred to as the "Public JRE") generally does not contain the server version of HotSpot. It also lacks the tools included with the JDK (JavaDB, javac, tools.jar, etc).

否则，运行时是相同的。另请注意，JDK可能会安装一个（或多个）JRE。

Otherwise, the runtimes are identical. Also, note that a JDK may install one (or more) JREs.

最后，所有上述说明都与Sun的Windows Java安装程序有关。其他供应商和平台可能（有时确实）有所不同。

Finally, all of the above notes are in regards to Sun's Java installers for Windows. Other vendors and platforms may (and sometimes do) vary.
