   Hi Cindy Liu (@yuyully), I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

   Suggestions to troubleshoot and work around the missing quick actions:

   • Verify editor and Java code‐action settings:
     • "editor.lightbulb.enabled": true
     • "java.errors.showInProblemsView": true
   • Confirm the Java Language Server is running without errors:
     • View → Output → select “Java Language Server” → look for startup errors
   • Trigger the import/code‐action via keyboard (e.g. Ctrl+. / ⌥⏎) while the editor cursor is on the error
   • Update VS Code and the Java extensions to the latest versions (1.27.0 → 1.x)

   Related issue worth checking:

   • No quick actions available when targeting class name in ctor invocation (similar missing code‐action behavior)
     No quick actions available when targetting class name in ctor invocation redhat-developer/vscode-java#2531

   The team will respond to your issue shortly. I hope these suggestions are helpful in the meantime. If this comment helped you, please give it a 👍. If the suggestion was not helpful or incorrect, please give it a 👎. Your feedback helps us improve!
