I have attempted to fix this problem using the various forums on this site, but nothing has helped. I tried similar techniques as used to fix other people's 1.8 errors, but nothing has worked. I have my java class file under my source folder and no imports, I just simply want a basic output message to make sure intelliJ is working as it should. Can anyone offer any advice?
Here change the language level to 1.8 or lesser. This changes the target release version.
Go to file -> settings -> Build Execution and Deployment -> Java -> Compiler
Here change the language level to 1.8 or lesser. This changes the source release version.
File -> Project Structure -> Module Settings -> Tab: Source: Language Level
and also here,
File -> Project Structure -> Project(In left pane) -> Project language level
