Java version is not changing on windows-CodePudding

Previously I had java 1.8.0_131, then I installed JDK 1.8.0_102. Then changed the version in environment variables also, but while checking java version in cmd it's still showing java 1.8.0_131. Any solution to this?

CodePudding user response：

I guess you have already tried the obvious ways with paths etc, so maybe you broke the symbolic links.

So, try to write the following commands in the terminal with elevated rights:

mklink java.exe "C:\Program Files\Java\jdk1.8.0_131\bin\java.exe"
mklink javaw.exe "C:\Program Files\Java\jdk1.8.0_131\bin\javaw.exe"
mklink javaws.exe "C:\Program Files\Java\jdk1.8.0_131\bin\javaws.exe"

(Adjust the path according to the paths of your computer)

Make sure that you have installed only 1 version of java 1.8 and uninstall the others in the control panel like this:

setx JAVA_HOME "%JAVA_HOME%"
set Path=%JAVA_HOME%\bin;%Path%
echo Java 8 activated as user default.
