Intellij random errors

Question

I have a few problems with IntelliJ since a few days now. He keeps giving me errors while they aren't really errors, my program runs fine and the errors are always the same. Mostly it's println , Override , LocalDate , Scanner and more.

How do I resolve this problem? Every time I open a new project he will do the same.

Answer 1

You need to define Project SDK, since you are using Java8 classes, set the ProjectSDK and language to Java 8.

Answer 2

Something is tangled here. Since you verified the SDK is set up correctly, can I suggest to just clear caches and Restart intellij.

Hope that helps!
