如何將函數添加到我的JButton中

Question

我試圖製作一個texttwist類型的遊戲，你得到了隨機字母，並且必須將它們變成單詞，類似於拼字遊戲。我需要弄清楚如何將功能添加到我的Jbuttons中進行，例如，清除按鈕清除猜測面板，或提交按鈕提交等

yourbutton.addActionListener(new ActionListener() { 
      @Override 
      public void actionPerformed(ActionEvent e) { 
       //you logic here 
      } 
     }); 
    }
