Intellij never suggest Java libraries

Question

I was trying to use List and Set on my code using Intellij. But Intellij only suggest classes under maven libraries, not JDK.

I can only use Java Collections(List, Set) by manually typing imports on the top of the file. so inconvenient.. please help

Make sure JDK is configured correctly for the project. Try to remove and then add JSDK again. You can also try File | Invalidate Caches and Restart, — CrazyCoder, Nov 07 '17 at 17:44

Verify that Project SDK is set:

Alternatively, try and create a simple Java Application and see if the problem persists. Then, try to re-import the maven project.

Hope this helps :)
