多個RadioButtons模擬器

Question

我正在嘗試製作一種簡單的足球模擬器。這是我看完教程後創建的代碼，我知道它很糟糕。我所要做的就是爲球隊增加一個價值，比如1分給最好的球隊，10分給最差的球隊，當我點擊模擬一個彈出窗口會顯示出告訴我哪支球隊會贏得球隊的價值。但我不知道如何去做。

public class sim extends JPanel { 

    public sim() { 
    // JFrame constructor 
     super(true); 

    JRadioButton chelsea, arsenal, chelsea2, arsenal2; 

    this.setLayout(new GridLayout(3,0)); 

    ButtonGroup group = new ButtonGroup(); 
    ButtonGroup group2 = new ButtonGroup(); 

    // takes image and saves it the the variable 
    Icon a = new ImageIcon(getClass().getResource("a.PNG")); 
    Icon c = new ImageIcon(getClass().getResource("c.JPG")); 


    chelsea = new JRadioButton("Chelsea",c); 
    chelsea.setHorizontalTextPosition(AbstractButton.CENTER); 
    chelsea.setVerticalTextPosition(AbstractButton.BOTTOM); 

    arsenal = new JRadioButton("Arsenal",a); 
    arsenal.setHorizontalTextPosition(AbstractButton.CENTER); 
    arsenal.setVerticalTextPosition(AbstractButton.BOTTOM); 

    group.add(chelsea); 
    group.add(arsenal); 

    JLabel label = new JLabel(""); 
    TitledBorder titled = new TitledBorder("Team 1"); 
    label.setBorder(titled); 

    chelsea.setBorder(titled); 
    arsenal.setBorder(titled); 

    JButton button = new JButton("Simulate"); 
    button.setHorizontalAlignment(JButton.CENTER); 
    add(button, BorderLayout.CENTER); 

    chelsea2 = new JRadioButton("Chelsea",c); 
    chelsea2.setHorizontalTextPosition(AbstractButton.CENTER); 
    chelsea2.setVerticalTextPosition(AbstractButton.BOTTOM); 

    arsenal2 = new JRadioButton("Arsenal",a); 
    arsenal2.setHorizontalTextPosition(AbstractButton.CENTER); 
    arsenal2.setVerticalTextPosition(AbstractButton.BOTTOM); 

    group2.add(chelsea2); 
    group2.add(arsenal2); 

    JLabel label2 = new JLabel(""); 
    TitledBorder titled2 = new TitledBorder("Team 2"); 
    label2.setBorder(titled2); 

    chelsea2.setBorder(titled); 
    arsenal2.setBorder(titled); 

    add(label); 
    add(chelsea); 
    add(arsenal); 

    add(button); 

    add(chelsea2); 
    add(arsenal2); 

    HandlerClass handler = new HandlerClass(); 
    chelsea.addActionListener(handler); 
    } 

    private class HandlerClass implements ActionListener 
    { 
     public void actionPerformed(ActionEvent e) 
     { 

      //JOptionPane.showMessageDialog(null, String.format("%s", e.getActionCommand())); 

     } 
    } 

    public static void main(String[] args) { 
    JFrame frame = new JFrame("Final"); 
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    frame.setSize(1920, 1080); 
    frame.setContentPane(new sim()); 
    frame.setVisible(true); 
    } 
}

將ActionListener放入sim類。

public void actionPerformed(ActionEvent e) 
    { 
     JButton clicked = (JButton)e.getSource(); 
     if(clicked == button) 
     { 
      JOptionPane.showMessageDialog(null, "this team will win"); 
     } 
    }
