   Hi Jinbo Wang (@testforstephen), 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.

   During debugging, the console evaluates expressions in the context of the current frame—which, inside a double-brace initializer, is the anonymous class—so your local variable ri isn’t in scope there. Workarounds:

   • Extract the map initialization outside the anonymous class:

   var ri = new HashMap<Character, Integer>();
   ri.put('I', 1);
   var c = ri.get(s.charAt(0));

   • Or use an immutable one-liner that doesn’t create an inner class:

   var ri = Map.of('I', 1);
   var c = ri.get(s.charAt(0));

   These approaches ensure ri is visible to the debug console. You can still inspect the map via the VARIABLES view if you prefer.

   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!
