@g00glen00b Yes .. I installed. I also checked java -version in my Command prompt. it is 18 only — sabari, Jul 16 '22 at 15:07
@sabari Did you also configured JDK 18 to be your Java home? — g00glen00b, Jul 16 '22 at 21:50

Since you're using IntelliJ, shared the screenshot and told us you alread checked the java version and I already got this error a few times here is my TODO I go through when I get this error:

Do what you showed us on the screenshot (Check Project Version and language level)
Do the same for Modules (Project Structure > Modules) Don't forget the Dependencies Tab there you can find the module SDK
Check Java Compiler (Settings > Build, Execution, Deployment > Compiler > Java Compiler) there you can see a Project bytecode version & Per-module bytecode version -> Check those

Hope this works :)
