因此，我一直在研究我的最終期限項目，即Connect Four遊戲。我遇到了這個問題，我相信我的CheckWin邏輯應該可以工作，當我運行該程序時，我沒有提供任何輸出。我在我的actionPerformed中調用了我的CheckWin（），並且我堅持要在這裏做什麼。作爲一個方面說明，有沒有什麼方法可以輕鬆增加JButton內部文本的大小？我想增加「X's」和「O's」的大小。如果這些都是簡單的修復，我在編程方面相對較新，所以很抱歉。我的代碼如下：連接Four Win Check不工作

謝謝！我在毆打自己這麼簡單的事情，對不起，我以前沒有意識到這一點。作爲一個便箋，你知道我可以如何增加我的X和O的字體大小嗎？我不知道如何去增加JButton中的字體大小。 – Smn21
