在降级到1.7之后，当我正在进行java -version时，我仍然看到Java 1.8 [英] I still see Java 1.8 when I am doing java -version after downgrading to 1.7

问题描述

我将java 1.7从1.8降级，但当我执行 java -version 时，我仍然看到1.8。我更改了路径，并将 JAVA_HOME 更改为1.7

I downgraded java 1.7 from 1.8, but I still see 1.8 when I do java -version. I changed the path and also made JAVA_HOME changed for 1.7 as

JAVA_HOME: C:\Program Files (x86)\Java\jdk1.7.0_79 
PATH:      C:\Program Files(x86)\Java\jdk1.7.0_79\bin

出于某种原因，我的道路上也有这个： C：\ProgramData \Oracle \ Java \ _javapath ，我相信保留这个1.8版本。当我从路径中取下这个时，我收到以下消息： C：\Program Files \ Java'\\jre7 \ lib \ amd64 \ jvm.cfg 。我不知道发生了什么事。任何建议都会非常有帮助。

For some reason I also have this in my path: C:\ProgramData\Oracle\Java\javapath, which I believe keeps this 1.8 version. When I take off this from the path, I get this message: C:\Program Files\Java\jre7\lib\amd64\jvm.cfg. I don't know what's going on. Any suggestion would be very helpful.

如果您的路径变量中有C：\ProgramData \ Oracle \ Java.atjavapath。然后打开
位置并确保java.exe文件指向相应的1.7目录。

Type "regedit" from startup menu. Take a back up if you are a novice.
Go to "HKEY_LOCAL_MACHINE->SOFTWARE->JavaSoft->Java Runtime Environment"
Double click on "CurrentVersion" on the right side of the panel
Change version to "1.7".

If you have "C:\ProgramData\Oracle\Java\javapath" in your path variable . Then open the
location and make sure the java.exe file points to respective 1.7 directory.
