Java'da radyo düğmelerini sıfırla

Question

Bir düğme grubunda üç radyo düğmesi var. Radyo düğmelerinin sıfırlanması için JButton tıklayın, böylece doldurulmuyor. Sizinle birlikte gelen mantıksal önerileri denedim. .set ve tüm booleanlar yapmak istediklerimi yapmadılar. Öyleyse, büyük takdir edilecek önerileriniz varsa. Teşekkürler!
