如何从main函数int java将文本追加到JTextArea？

Question

I want to append some text to JTextArea from main function, but it doesn't work.

I am appending text from init() and from main() , but only text from init() appears on JTextArea .

public class Test extends JApplet{

    private static JPanel panel = new JPanel();
    private static JTextArea textArea = new JTextArea();

    public void init() {   

        panel.setLayout(null); 
        panel.setPreferredSize(new Dimension(400,300)); 
        this.add(panel);

        textArea.setBounds(20, 150, 350, 100);
        panel.add(textArea);

        setTextArea("BBBB");
    }

    public static void setTextArea(String text){
        textArea.append(text);
    }
    public static void main(String args[]) {        
        setTextArea("AAAAA");
    }   

}

I'm getting textarea just with "BBBB".

UPDATE

I have one more function. I am calling it from init() , text is appending and everything is fine. But if I put a line setTextArea("some text"); after line clientSocket = new Socket(address, port); , text won't append.

 private static void connetToServer() throws IOException, InterruptedException {
        try {
            //address = args.length > 0 ? args[0] : "localhost";
            //port = args.length > 1 ? Integer.parseInt(args[1]) : 4444;
            //System.out.println(address + ' ' + port);
            setTextArea("some text");
            clientSocket = new Socket(address, port);
            output = new PrintStream(clientSocket.getOutputStream());
            input = new DataInputStream(clientSocket.getInputStream());
            inputLine = new DataInputStream(new BufferedInputStream(System.in));
        } 
        catch( IOException e){
            setTextArea("Can't connet to server");
            System.exit(0);
        }
     }

You're getting "BBBB" appended to your text area because the init method is used as an entry point for applets and servlets .

Your class extends JApplet which is a subclass of java.applet.Applet meaning it will use init and not main (which is instead used as an entry point for applications).
