我希望通过复制Java文件夹的内容并设置环境变量来确保一切都能正常工作。
我通常在虚拟机中运行安装程序，压缩\java文件夹内容，回到虚拟机的快照，然后解压缩压缩文件。
我找不到一个地方有最新的JRE / JDK压缩文件…
http://java.sun.com/javase/downloads/index.jsp
http://download.java.net/jdk6/
另外，假定sun的exe安装程序只是解压缩整个文件，而不会弄乱注册表、环境变量等等，这是否安全?

You can just use 7zip (or another similar app) to get the dirs inside the core.zip file that's bundled in the installer. Just use 7zip to browse the exe, you'll see a core.zip file which has all the files that usually go inside "jreX" dir (where X is the major version number). As for setting env variables and the such, you can follow the other answers. If all you want is a portable jre (for example, you can run your jars by using java.exe jarfile or javaw.exe jarfile) then this solution will do. This is very similar to copying the jre dir from one place to another

针对Windows x86、Windows x64、Linux x86、Linux x64、Mac OS X x64、Solaris x64等操作系统，Oracle网站上有JRE的.tar.gz文件。 参见:http://www.oracle.com/technetwork/java/javase/downloads/jre8 -下载- 2133155. - html
还有Java开发工具包(JDK): http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html。 Windows .tar.gz。没有，但是您可以用7zip之类的工具提取.exe文件。
我发现这对于使Eclipse可移植非常有用。: -)
The Process described by Igor and CharlesB Works to me, since IDE's like NetBeans and Eclipse permit specify the location of the JDK, even software like Apache Tomcat (the ZIP Distribution) use BASH - FILES to set it up (then specify the JDK location using relatives URI). I Have a USB-HardDisk With NetBeans, Eclipse, Apache Tomcat working with a JDK in "portable mode". I Had a way to extract a copy of the JDK from the installers files: Install it, Copy it in other place and then uninstall it. A dirty way to extract it, but was successfull. The place to put EXTRA - LIBS was: %PLACE_WHERE_JDK_ARE%\jre\lib\ext

在这里。下载.gz包。
mkdir c:\JDK
cd c:\JDK
git clone https://bitbucket.org/ramazanpolat/jdk-8u112-windows-x64/
or
git clone https://bitbucket.org/ramazanpolat/jdk-8u112-windows-x86
这里是JDK 5 zip文件的链接。 sun-jdk-5-win32-x86-1.5.0.12.zip
