I have checked this link but did not find any solution.

Answer 1

To know the location of the executable being launched, try :

where java.exe

And

where javac.exe

You should see the corresponding path .

Answer 2

I ran

where javac.exe

I gave two path.

i ran echo %path% it gives alot of lines.

older JDK path was set also in path variable in system variable path section but latest jdk was set in user defined path variable so i removed the older version from system variables.
