java - 是否有可能将 JPanel 对象存储在 arraylist 中

Question

嗨，我从团队领导那里得到了一项任务，即存储用户在文本字段中输入的员工详细信息，无论该面板中的内容如何，​​之后在另一个框架中，管理员必须通过调用数组列表来检查每个员工的详细信息，该列表应在卡片布局中显示面板，这是我的员工注册编码。任何人都可以帮助我

Registration()
{
    frm=new JFrame("Welcome to the login page");
    left=new JPanel(new GridLayout(0,1));
    left.setBackground(Color.LIGHT_GRAY);
    right=new JPanel(new GridLayout(0,1));
    right.setBackground(Color.LIGHT_GRAY);
    sp=new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,left,right);
    lb9=new JLabel("Member");
    lb9.setFont(new Font("Serif",Font.PLAIN, 18));
    lb9.setForeground (Color.blue);
    lb10=new JLabel("Create an Account");
    lb10.setFont(new Font("Serif", Font.PLAIN, 16));
    lb10.setForeground (Color.blue);
    lb1=new JLabel("Username");
    tf1=new JTextField(10);
    lb2=new JLabel("Password");
    tf6=new JTextField(10);
    lb3=new JLabel("First Name");
    tf2=new JTextField(10);
    lb4=new JLabel("Last Name");
    tf3=new JTextField (10);
    lb5=new JLabel("Password");
    psd2=new JPasswordField (10);
    lb6=new JLabel("Confirm password");
    psd3=new JPasswordField (10);
    lb7=new JLabel("MailID:");
    tf4=new JTextField (10);
    lb8=new JLabel("Contact No");
    tf5=new JTextField (10);
    b1=new JButton("Enter");
    b2=new JButton("Register");

}
public void launchFrame()
{


frm.setSize(450, 350);
frm.add(sp);
//sp.setLeftComponent(left);
//sp.setRightComponent(right);
left.add(lb9);
left.add(lb1);
left.add(tf1);
left.add(lb2);
left.add(tf6);
left.add(b1);


right.add(lb10);
right.add(lb3);
right.add(tf2);
right.add(lb4);
right.add(tf3);
right.add(lb5);
right.add(psd2);
psd2.setEchoChar('*');
right.add(lb6);
right.add(psd3);
psd3.setEchoChar('*');
right.add(lb7);
right.add(tf4);
right.add(lb8);
right.add(tf5);
right.add(b2);

frm.setVisible(true);
}

像这样创建List对象

List<JPanel> panelList = new ArrayList<JPanel>();

// add your JPanel object like this way
panelList.add(yourPanel);

// retrieve your JPanel object from list
JPanel panel = panelList.get(index);
