On a Mac, you can use terminal to go to /Applications/Android Studio.app/Contents/jre/jdk/Contents/Home (or wherever your Android SDK is installed) and enter the following in the command prompt:

In Android Studio 4.0.1, Help -> About shows the details of the Java version used by the studio, in my case:

Answer 5

You can use cmd + ; for Mac or Ctrl + Alt + Shift + S for Windows/Linux to pull up the Project Structure dialog. In there, you can set the JDK location as well as the Android SDK location.

To get your JDK location, run /usr/libexec/java_home -v 1.7 in terminal. Send 1.7 for Java 7 or 1.8 for Java 8.
