What's the proper way to compare a String to an enum value?

Homework: Rock Paper Scissors game.

I've created an enumeration:

      enum Gesture{ROCK,PAPER,SCISSORS};

from which I want to compare values to decide who wins--computer or human. Setting the values works just fine, and the comparisons work properly (paper covers rock, rock crushes scissors, scissors cuts paper). However, I cannot get my tie to work. The user is declared as the winner any time there's a tie.

Ahhh...crap...this will clarify: userPick is a String with values rock, paper, or scissors. I'm unable to use == to compare userPick to computerPick, which, as you can see below, is cast as type Gesture from my enum.

      if(computer == 1)
         computerPick = Gesture.ROCK;
      else
         if(computer == 2)
           computerPick = Gesture.PAPER;
         else
           computerPick = Gesture.SCISSORS;
      if(userPick.equals(computerPick))
       {
          msg = "tie";
          ++tieGames;
       }
           etc....

I am guessing that there's an issue with rock not being equal to ROCK, or the String userPick not being able to match Gesture computerPick because the latter isn't a String. However, I'm not able to find an example of a similar circumstance in my textbook or Oracle's Java Tutorials, so I'm not sure how to correct the problem...

Any hints?
