Placing an actor by using another actor

Bambus

is there a way to playce an actor by pressing an actor which is holding

if (Greenfoot.mouseClicked(this)){

}

I already saw the post from Lucius (https://www.greenfoot.org/topics/59309/0) but I didn't really understand how to place the new actor.

if (Greenfoot.mouseClicked(this))
{
Objectt obj = new Objectt();
getWorld().addObject(obj, getX(), getY());
}

thank you :D So.. I have tried it and it works.. but somehow I can't remove the actor by using

getWorld().removeObject(obj);

. I wrote

Object obj = new Object();[

at the beginning of the green box (sorry.. I don't know what it is called )

So I tried but then there is on the addObject and removeObject line an error (cannot find symbol - variable obj).
