I am using eclipse for android app development. I didn't get any error or anything while creating android applications or simple core java programs.

I cannot find `jdk` on my system windows 7, only `jre6` is there.

I tried the below command but i didn't get any path :

```
C:> for %i in (javac.exe) do @echo.   %~$PATH:i

```

I have searched for `javac.exe` in my c drive but didn't find. There are only two folder in `C:\Program Files\Java`: `jre1.6.0_18` and `jre6`

How can I find the path of jdk on my system ?
