How do I fix the 'Cannot resolve symbol' error in IntelliJ?

This error usually occurs when IntelliJ can't find the class or method you're trying to use. Here are a few steps to troubleshoot it:

1. Ensure that your project is correctly configured and all dependencies are included.
2. Try invalidating caches by going to File > Invalidate Caches / Restart.
3. Check if the file is in the correct source folder.

I checked the dependencies and they seem fine. What else can I do?

If the dependencies are correct, try the following:

1. Rebuild your project by going to Build > Rebuild Project.
2. Make sure the file is not excluded from the project.
3. Check for any syntax errors in your code that might be causing the issue.

I rebuilt the project, but the error persists. Any other suggestions?

You can also try:

1. Updating IntelliJ to the latest version.
2. Checking your JDK settings under File > Project Structure.
3. If you're using Maven or Gradle, ensure that your project is synced properly.

Thanks! I’ll try those steps and see if it resolves the issue.
