    }

}

To add lives in your character class you first need a variable to save the current live state. Now you need to count down this value when your actor looses lives and check whether the actor has no lives anymore. When do you want your actor to loose a live?

To add the variable you can use this code: 
public class PBear extends Actor  
{
    private int lives = 10;//or any other starting number;

    //the rest of your code;
}
To make your actor loose a live when it hits another actor is easy. Try it like this: 
//put this code in the act method of your PBear calss;
if (getOneIntersectingObject(OtherObject.class) != null) {
    lives--;
}
The only problem is that after you lost a live the actor will still be there and your actor will get hurt again. Do you want to remove the other actor after it has hit your actor? (that would be the easyest way) If so you can use this code: 
//put this code in the act method of your PBear calss;
Actor intersectingEnemy= getOneIntersectingObject(OtherObject.class)
if (intersectingEnemy!= null) {
    lives--;
    getWorld().removeObject(intersectingEnemy);
}
