((RandomPicker)getWorld().getObjects(RandomPicker.class).get(0)).pop();
Broken down, this becomes (assuming there is at least one random picker in the world): 
List<Objects> pickers;
pickers = getWorld().getObjects(RandomPicker.class);
RandomPicker randomPicker;
randomPicker = (RandomPicker) pickers.get(0);
randomPicker.pop();
When using the last codeset, you would need to 'import java.util.List;'.
