获取当前jre的文件路径 [英] get current jre's file path

问题描述

假设我们有两个Java应用程序A和B.应用程序A将调用应用程序B. 应用程序A已启动，但是当A调用B时，我不知道java_home或任何其他jre路径，我想获取运行在哪个jre应用程序A上，返回jre的执行文件的路径，这可能吗?

推荐答案

您可以通过请求系统属性java.home:

You can get the installation directory for the JRE by requesting the system propertie java.home:

String jrePath = System.getProperty("java.home");
