[英]java -version different than expected
I'm having a problem with determining what version of java am I using:) cmd.exe
is using java.exe
from C:\\WINDOWS\\system32
as specified in Path
environment variable. 我在确定我使用的Java版本时遇到问题:) cmd.exe
正在使用Path
环境变量中指定的C:\\WINDOWS\\system32
java.exe
。
C:\WINDOWS\system32>java.exe -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode)
But in windows when I right-click on that file and select Properties->Version->Full Version
it says 1.6.0_22-b04
. 但是在Windows中,当我右键单击该文件并选择Properties->Version->Full Version
它显示为1.6.0_22-b04
。
Why? 为什么?
This means you have two installations. 这意味着您有两个安装。 Check your c:\\program files\\Java
folder. 检查您的c:\\program files\\Java
文件夹。 Also check your PATH environment variable - it should point to the correct path. 还要检查您的PATH环境变量-它应该指向正确的路径。
Change to a directory which is not in your PATH environment variable and run java -version
. 切换到不在PATH环境变量中的目录,然后运行java -version
。 Note that the current directory always is the first entry in PATH
. 请注意,当前目录始终是PATH
