[英]Java pre-installed in Windows and Linux?
我知道Java已预装在Mac OS X中,但我想知道它是否已预装在Windows XP,Vista,7和所有Linux发行版中吗?
Java isn't preinstalled in any Windows version (OEM not included - depends on the manufacturer then). 没有在任何Windows版本中预安装Java(不包括OEM-然后取决于制造商)。
I think it is not common in Linux distributions at all, but I don't want to make a general statement about ALL distros here ;-) 我认为这在Linux发行版中根本不常见,但是我不想在这里对所有发行版进行一般性陈述;-)
Fedora Linux附带了开源Java IcedTea 。
Some Linux versions I experienced comes with old versions of Java JDK (so you must take care developing for these distributions!) or with an alternative version of the compiler: Gnu Compiler Java (GCJ). 我遇到的某些Linux版本是Java JDK的旧版本附带的(因此您必须小心开发这些发行版!)或编译器的替代版本:Gnu Compiler Java(GCJ)。
About the virtual machine, I've just seen the JVM in Windows and Linux, provided by Sun. 关于虚拟机,我刚刚看过Sun提供的Windows和Linux中的JVM。
I understand that the vast majority of PCs come with the Sun JRE installed. 我知道绝大多数PC都装有Sun JRE。 There was a bit of a law suite between Microsoft and Sun (my employer, now a wholly owned subsidiary of Oracle).
微软和Sun(我的雇主,现在是Oracle的全资子公司)之间存在一些法律诉讼。
The "6-open" OpenJDK is a backport of the GPLed JDK7. “ 6-open” OpenJDK是GPLed JDK7的反向端口。 General purpose distros should include it, but of course with Linux you are fighting with package management.
通用发行版应该包括它,但是对于Linux,您当然要与软件包管理作斗争。
