4,432 PointsI feel like I'm so close but keep getting this error "./QuickFix.java:22: error: cannot find symbol Map newMap??
I feel like my solution is right (or very close at least) but I keep getting an error on line 22 of the QuickFix doc which is where I initialized the HashMap. Error is:
./QuickFix.java:22: error: cannot find symbol Map newMap = new HashMap<>();
I've seen some solutions on the forum that have used the TreeMap but I'd like to know why my solution is not passing...because it's driving me crazy.
Thanks guys

Treehouse TeacherHi there! You are getting close. It's reporting that it can't find HashMap
because it can't. To use a HashMap
, you must first import the class to do so.
import java.util.HashMap;
You will need to include this in the appropriate place for it to stop complaining that it can't find it
Hope this helps!
