Multiple menu items != multiple event handlers?

Question

I'm developing a program whereby a user can rate how much they like certain images when displayed on screen. The bulk of the work is done, but my rating mechanism (first attempt at one) is currently a right-click pop-up menu with the values 1-10 in ten menu items - naff I know, but its early design stages ;)
This brings obvious problems, and I don't want to have to code event handlers for each and every Menu item just to set the same parameter to a different value depending on which menu item the user clicked (i.e. I don't want to have to create an event for the first menu item that simply sets and int variable to 1, and do the same for #2 through 10). What I was wondering was, is there any simpler way of implementing this? I.e. can I use the same event for the whole popup menu and detect the value of the option clicked and set the value accordingly? This would also mean, should I need to extend the rating scale above ten, say perhaps to twenty, then there would be no further coding necessary (which is nice! Lol!).
Can anyone offer any suggestions? I did search, but tbh didn't have a clue what to search for. Your advice is appreciated.

Implement the ActionListner that allows the constructor to take an argument as to the rating of the menu item, and then set the required rating variable to this when called. For example
class MyRatingSystem
    int rating = 0;
    public void createMenus()
        JMenu ratings = new JMenu("Ratings");
        for(int i = 0; i < 10; i++)
            JMenuItem rating = new JMenuItem("Vote: " + i);
            rating.addActionListener(new RatingListener(i));
            ratings.add(rating);
    class RatingListener imlpements ActionListener{
        final int rate;
        public RatingListener(int rate)
            this.rate = rate;
        public void actionPerformed(ActionEvent ae)
            rating = this.rate;
}The above code is inefficient and is only there to serve the purpose of an example(look at the loop, although I would think the compiler could do some loop unrolling?)
