java - 两个标签位于中心的中间

Question

我想在窗口的中央放置两个标签。我让它使用 1 个标签和以下代码:

public static void main(String[] args)
{
    JFrame contentPane = new JFrame();
    contentPane.setBounds(100, 100, 450, 300);
    JPanel centerPanel = new JPanel(new BorderLayout()); 

    JLabel label = new JLabel("center1");
    centerPanel.add(label, BorderLayout.CENTER); 

    contentPane.add(centerPanel, BorderLayout.CENTER);
    contentPane.setVisible(true);
}

现在我想要第一个标签旁边的另一个标签。我尝试使用 flowlabel，但它们被放置在 BorderLayout.CENTER 的顶部

public static void main(String[] args)
{
    JFrame contentPane = new JFrame();
    contentPane.setBounds(100, 100, 450, 300);
    JPanel centerPanel = new JPanel(new BorderLayout()); 

    JLabel label1 = new JLabel("center1");
    JLabel label2 = new JLabel("center2");

    JPanel flowPanel = new JPanel(new FlowLayout());
    flowPanel.add(label1);
    flowPanel.add(label2);

    centerPanel.add(flowPanel, BorderLayout.CENTER); 

    contentPane.add(centerPanel, BorderLayout.CENTER);
    contentPane.setVisible(true);
}

谢谢!

使用无约束的 GridBagLayout:

   JPanel centerPanel = new JPanel(new GridBagLayout()); 

   JLabel label1 = new JLabel("center1");
   JLabel label2 = new JLabel("center2");

   JPanel flowPanel = new JPanel(new FlowLayout());
   flowPanel.add(label1);
   flowPanel.add(label2);

   centerPanel.add(flowPanel);
