In order to do some JNI programming, I need to know where Java installed on my Mac.

(为了做一些JNI编程，我需要知道在Mac上安装Java的位置。)

I thought that inside the /Library/Java/JavaVirtualMachines/ folder, there would be a folder called 1.7.0.jdk or something, but then I found that the folder is empty.

(我认为在/Library/Java/JavaVirtualMachines/文件夹中，会有一个名为1.7.0.jdk的文件夹，但后来我发现该文件夹是空的。)

This was confirmed by running ls /Library/Java/JavaVirtualMachines/ in the Terminal.

Answer 1

Use /usr/libexec/java_home -v 1.8 command on a terminal shell to figure out where is your java 1.8 home directory

(在终端shell上使用/usr/libexec/java_home -v 1.8命令来确定java 1.8主目录的位置)

If you just want to find out the home directory of your most recent version of java, omit the version.

(如果您只想查找最新版本java的主目录，请省略该版本。)

eg /usr/libexec/java_home

(例如/usr/libexec/java_home)
