How to dynamically select which variable to return in if else statement

Since you can't select more than one value to return in Java, I was wondering how I could set my method to return the correct value based on the if else statement. How I have it now with a return in each if statement probably isn't correct but I'm not sure of an alternative. I think the code is just choosing the first return statement and closing the program. What would be an alternative? Thanks

public int rockGame()
       {
           if (compChoice == 0)
           {
               txaResults.append("Rock vs Rock equals a tie! \n");
               return result3++;
           }
           else if (compChoice == 1)
           {
               txaResults.append("Paper Covers Rock (Computer Wins)! \n");
               return result2++;
           }
           else if (compChoice == 2)
           {    
               txaResults.append("Rock smashes scissors (You Win) \n");
               return result1++;
           } 
           return 0;
       }

here's my code. It's an actionListener so when I hit a button I want the respective method with it's return value to run. Eventually, I'll have it output to a JTextField if all goes to plan. Right now when I hit a button, I get the same outcome, the first condition, for each method like rockGame(), paperGame(), etc.

   { 
        Random random = new Random();
        int compChoice = random.nextInt(3);
        int result1 = 0; //user wins
        int result2 = 0; //computer wins
        int result3 = 0; // tie

        public int rockGame()

           return 0;
       }
