So this is code for button to append arraylist in textField.



And there are all classes:
Runner.class where ArrayList is defined.




Rame.class where frame is created with buttons and other things:



and game.class (Propably you are not interested with this one.)

So arraylist is null at rame.class works fine at runner.class.

In this code you are creating a new Runner, which will have an empty List (line 21 of your Runner code above).

I'm not too sure what it is you are trying to do, so can't offer a suggestion at the moment.
