If you are facing this kind of issue even after you update your jdk version and change the path as well. What you can do is change the run configuration setting. You can access this by running the program, then on the run window beside the rerun option there would be 4 more options, you can click on the last option which is a 3 dots hamburger symbol it presents you with an option Modify RUN Configurations click on it, then you can change the JDK version path.
