java - 从 ActionPerformed 中的另一个类导入代码

Question

我得到了这个带有按钮的 JFrame。
我添加了 ActionPerformed 添加，就像它应该的那样。
但我的一个按钮执行很长的代码，我想将其移动到一个单独的类，然后将其导入到 AP()。

这可能吗？ (按钮名称的含义，JButton 之类的东西......)。

公共(public)类 Frame 扩展 JFrame{

public JButton News;

    public boolean TP_B = false,
               MC_B = false;

    Icon News_img = new ImageIcon(this.getClass().getResource("/onglet/News.png"));

            Minecraft_JSP = new JScrollPane(Minecraft_JEP);
            Minecraft_JSP.setBounds(67, 27, 798, 465);
            Minecraft_JSP.getVerticalScrollBar().setUnitIncrement(10);

            add(Minecraft_JSP);
        }

}

好的，这就是 Frame 类(我只留下了相关按钮的代码)。

当新闻按钮将显示这些 TP 和 MC 按钮时。

当点击其中一个时，它将显示新闻(此处为 TechPack:我的服务器或 Minecraft 新闻)

我想要的是 if(e.getSource() == TP) 中的所有代码都在一个单独的类中(称为 News_TechPack)

请记住，我使用这个 Main 类而不是您的 Frame 类。你也可以用你的。还要考虑不要将行为写入单独的类中，而只写入 Frame 类中的函数中。通过这个示例，您应该能够自己编写函数。

public class Main implements ActionListener{

    JFrame f;
    JButton button;

    boolean TP_B = false;

    ButtonBehaviour bb;

    public Main()
    {
        bb = new ButtonBehaviour(this);
        f = new JFrame();

        f.setSize(400,400);
        f.setLocationRelativeTo(null);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        button = new JButton("Test");

        button.addActionListener(this);
        f.add(button);


        f.setVisible(true);
    }

    public static void main(String[] args) throws IOException {
        new Main();
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if(e.getSource() == button)
        {
            System.out.println("Call the specific function in your behaviour class");
            bb.buttonBehaviour();
        }

    }


}

class ButtonBehaviour{

    Main m;

    public ButtonBehaviour(Main pMain)
    {
        m = pMain;
    }

    public void buttonBehaviour()
    {
         System.out.println("TP");

         m.TP_B = true;

         //Write here your rest behaviour.
         //Keep in mind to use your Main instance or Frame instance
         //for calling and changing your specific variables.
         //you could also just create your
         //buttonBehaviour-Functions in your Frame class. Would
         //be easier
    }
}
