java version is wrong

Possible reasons:

# In the path of ##path, some path directories also contain java.exe, and then the path is in front of

%JAVA_HOME%\bin, so the java.exe in the previous path is preferred when running, so No matter how you change JAVA_HOME, java -version remains unchanged

Solution:

After modifying JAVA_HOME, add %JAVA_HOME at the front of the path %\bin;To ensure that JAVA_HOME is referenced first.
