Change objects between 2 Vectors

Question

Voor mijn programma gebruik 2 Vectors (in klasse Schuif en Speelveld). In deze Vectors staan objecten van de klasse Steen (Een canvas, vierkantje met achtergrond).
How do I change a object Stone in Vector Playfield to Vector Slider and
substitute it for the first object Stone in Vector Slider and the substituted object Stone comes in for object Stone in Vector Playfield.
Vector Playfield Vector Slider
| | Steen | |
| | <----------> | |
| | | |
Or can i use something better than Vectors, like ArrayList???
I hope it's a little bit clear :S
Thanks in advance

Answer 1

Here is some of my code. Here i want to change 2 stones from place. This doesnot even work :-S
When I call the method verPlaatsStenen(), my app is hanging... :-S
How can i change 2 stones from place, just on the Playfield.
