java中的GUI

我有一段在eclipse上正常工作的代码

class clienttime_gui
{
    public static void main(String args[]) throws Exception
    {   
        JFrame frame=new JFrame("Add IP");
        JTextField textbox;
        JButton button;
        JLabel label;
        frame.setLayout(null);
        textbox = new JTextField();
        textbox.setBounds(100,20,150,20); 
        label = new JLabel("Add IP");
        label.setBounds(50, 20, 100, 20);
        button=new JButton("Submit");
        button.setBounds(250,20,100,20);
        frame.add(textbox);
        frame.add(label);
        frame.add(button);
        final String x=textbox.getText();
       frame.setSize(400,100);
        frame.setVisible(true);  
        button.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                if (SwingUtilities.isLeftMouseButton(e) && e.getClickCount() == 1) {
                    try{

                    InetAddress locIP = InetAddress.getByName(x);
                    //InetAddress locIP = InetAddress.getByName("14.139.60.104");
                    Socket soc= new Socket(locIP,7681);
                    BufferedReader in=new BufferedReader(new InputStreamReader(soc.getInputStream()));
                    String y= null;
                    while((y = in.readLine()) != null){
                    System.out.println(y);
                    }
                    }catch(Exception e1){}
                }
            }
        });       
   }
}

这是我的用户界面

现在我正在eclipse控制台中获取输出，但我想将其放入框架中，我应该怎么做？

添加一个开头没有文本的JLabel，并在每次提交新ip时对其进行编辑。

声明一个

JLabel

并调用

setText

，而不是

System.out.println

 label.setText(y);

您可以使用

setText（“youString”）

。。尝试学习

        label = new JLabel("Add IP");
        label.setBounds(50, 20, 100, 20);
        button = new JButton("Submit");
        button.setBounds(250, 20, 100, 20);

我知道，但我不能将这行System.out.println（y）传递给字符串来执行此操作。label.setText（string.valueOf（y）），请将服务器/客户端放在单独的线程中，否则gui线程将被阻塞。我知道，但我不能将这行System.out.println（y）传递给字符串来执行此操作。label.setText（string.valueOf（y））请将您的服务器/客户端放在一个单独的线程中，否则您的gui线程将被阻塞。
