Koduję program, który jest grą z pamięcią 4x4. W tych 16 polach będzie para liczb całkowitych od 0-7. Mam już wszystko losowo i poprawnie zakodowane. Teraz próbuję dowiedzieć się, jak sparować kolory z odpowiednimi liczbami całkowitymi za każdym razem, gdy kliknie myszą nad polem.

Tutaj większość kodu. Wiem, że logika dla tej gry nie została jeszcze rozpoczęta, ale teraz bardziej koncentruję się na metodzie displayHit i setColor. Po prostu opublikowałem cały kod, bo może zawiedłem gdzieś indziej.
