如何向我的 JButton 添加功能 [重复]

Question

我正在尝试制作一个 texttwist 类型的游戏，你可以在其中随机获得字母，然后将它们变成单词，有点像拼字游戏。我需要弄清楚如何在我的 jbuttons 中添加一个功能，例如，清除按钮清除猜测面板，或者提交按钮提交它等等。

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