Question

I have a list full of many classes and in each class I would like to know a way that allows me to remove itself like this:

public class World{
    List<Entity> Entities;
}
public class Entity{
    public void removeselffromlist()
    {
        //code i dont know
    }
}

Edit:There will not be multiple worlds

Answer 1

You would have to make the list available to the other class. One possible solution would be:

public class World {
    List<Entity> entities;

    public void removeItem(Entity entity) {
        entities.remove(entity);
    }
}

public class Entity{
    public void removeSelfFromList() {
        world.removeItem(this);
    }
}

Note that you would need to have a “world” object somewhere.
