Answer 1

If you don't happen to have a JDK installed you can download the latest version here

You can unpack it to your home directory so that you don't need extra permissions:

~/Downloads$  tar zxvf jdk-<version>-linux-x64.tar.gz -C ~/java/jdk/

And finally reference your new JDK on IntelliJ:

Answer 2

Alt+ Ctrl + Shift + S - Project

Answer 3

To find the path where java is installed on ubuntu, you can run the following command from terminal:

$ whereis java

You may get something like this:

java: /usr/bin/java /etc/java /usr/share/java /usr/lib/jvm

Which means that the java resides at one of the above paths as for example /usr/bin/java

So, that directory should designate in IntelliJ. You can configure in the Project Structure, press Ctrl + Alt + Shift + S, choose Platform Settings -> SDKs, click on green button (+), select the home directory for JDK.
