Witam, w javie jestem początkujący. Piszę grę planszową, mam 20 pól które są buttonami. Niestety nie wiem w jaki sposób wykonać przejście gracza na kolejne losowe pole (losowy button na planszy). Każdy button ma akcję kliknięcia, która ładuje informacje na temat danego pola. Niestety nie wiem jak dynamicznie wywoływać te buttony. Próbowałem operować nimi w tablicy, niestety pojawia się błąd
"AWT-EventQueue-0".

Pokaż jakiś kod, może uda się pomóc.

Z każdą pozycją z listy lista_pol chcę powiązać buttona, tak aby wywołać button zgodny z numerem pozycji. Próbowałem z tablicą buttonów, niestety wywala błąd (post początkowy).
W metodzie zmiana_pola chciałbym wywoływać button po numerze
