Answer 4

I think the right way to find the internal Java used by the Android Studio is to

1. Open Android Studio
2. Go to File->Other Settings->Default Project Structure/JDK Location:
3. and copy what ever string is specified there

This will not require memorising the folder or searching for java and also these steps wil take of any future changes to the java location by the Android Studio team changes I suppose

Answer 5

It is located on the Android Studio folder itself, on where you installed it.

Answer 6
