推荐答案
这取决于您的打包系统...如果java命令有效，则可以键入readlink -f $(which java)来查找java命令的位置.在我现在使用的OpenSUSE系统上，它返回/usr/lib64/jvm/java-1.6.0-openjdk-1.6.0/jre/bin/java(但这不是使用apt-get的系统).
This depends a bit from your package system ... if the java command works, you can type readlink -f $(which java) to find the location of the java command. On the OpenSUSE system I'm on now it returns /usr/lib64/jvm/java-1.6.0-openjdk-1.6.0/jre/bin/java (but this is not a system which uses apt-get).
在Ubuntu上，它看起来像在 /usr/lib/jvm/java-6-openjdk/中(对于OpenJDK，在其他版本中) Sun JDK的/usr/lib/jvm/的子目录(我认为还有其他实现).
On Ubuntu, it looks like it is in /usr/lib/jvm/java-6-openjdk/ for OpenJDK, and in some other subdirectory of /usr/lib/jvm/ for Suns JDK (and other implementations as well, I think).
对于任何给定的软件包，您都可以通过查询dpkg来确定它安装了哪些文件以及将它们安装在何处.例如，对于软件包'openjdk-6-jdk':dpkg -L openjdk-6-jdk
For any given package you can determine what files it installs and where it installs them by querying dpkg. For example for the package 'openjdk-6-jdk': dpkg -L openjdk-6-jdk
