我与intelij合作，我想做的是：

当按下panel1按钮时，右J面板应打开panel1，并与Panel2按钮类似，但出现的是一些小正方形。
代码：

GridBagLayout layout = new GridBagLayout();
Panel1 p1;
Panel2 p2;
private JButton panel1Button;
private JButton panel2Button;
private JPanel DynamicPanel;
private JPanel mainPanel;

public Frame1(){
    p1 = new Panel1();
    p2 = new Panel2();

    DynamicPanel.setLayout(layout);
    GridBagConstraints c = new GridBagConstraints();
    c.gridx = 0;
    c.gridy = 0;
    DynamicPanel.add(p1);
    c.gridx = 0;
    c.gridy = 0;
    DynamicPanel.add(p2);
    p1.setVisible(false);
    p2.setVisible(false);

    panel1Button.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            System.out.println("Button1");
            p1.setVisible(true);
            p2.setVisible(false);
        }
    });
    panel2Button.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            System.out.println("Button2");
            p1.setVisible(false);
            p2.setVisible(true);
        }
    });
}

我还想在不同的类中分离p1和p2面板。panel1和panel2如下所示：
