I have one error can't sort it out

My workspace is saying I have one error and I can't figure out what is causing it. It's in line 65

./com/teamtreehouse/Treet.java:65: error: cannot find symbol         
        List<String> results = new ArrrayList<String>();             
                                   ^                                 
  symbol:   class ArrrayList                                         
  location: class Treet                                              
1 error

You have an extra 'r' in ArrayList. Just remove one of the r's and you should be good to go.

List<String> results = new ArrrayList<String>();

should be

List<String> results = new ArrayList<String>();

Get ready to slap yourself on the forehead....there are only two r's in ArrayList, not three:).

I didn't realize it until I had gone through all your code lol.

No problem, we've all done it! This is why IDEs were invented, right:)?
