Use an int field to track the current direction ( '1' for moving down and '-1' for moving up). The field can be multiplied by the speed and added to the current y-coordinate to get the new y-coordinate of the actor. If an edge is encountered, multiply the field by '-1' to change its direction of motion.

private int direction = 1;
public void act()
{
    setLocation(getX(), getY()+direction);
    if (isAtEdge()) direction *= -1;
}
