How to check which world actor is in?

In the actors act() method, I am trying to make it's actions differ, depending on the world it's in. 
if (Greenfoot.mouseClicked(this))
        {
         
            if (this.getWorld() == Room11)
            {
            //further actions}
       
    }
I know why this doesn't work but how do I only return the name of the world, so I can compare? I only want the actor to perform certain actions if it's on a particular world.

this should work 
try
        {
            World world = (Room11) getWorld();
            //further actions
        }catch (ClassCastException x) {}

Thank you so much, I was afraid I would have to make new objects for each world or something xD

Rather than having to deal with the ClassCastException when the world is not a Room11, you could just say: 
if (this.getWorld().getClass() == Room11.class) {
    // further actions
}

I believe that 
if (getWorld() instanceof Room11)
would also work.

Yes it would. The only difference is that instanceof is true if the World is of class Room11 or any subclass of Room11., for example, if you have "class Room11a extends Room11". Which may or may not be what you want.
