Idea project startup solution

Many people on the Internet said that the JDK was not installed correctly. At first, they suspected that the JDK was not installed in the default directory, so they reinstalled it and configured the JDK environment. But still report an error. The JDK is re imported in idea again, but it still doesn’t work.

Many methods failed. Finally, it was found that the default project language level was 16 (the idea version used by bloggers was 2021), so it was changed to 8 and the error was reported.
