Hi,
I have add a button and textfield like
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;
public class test2 {
     public static String srg="";
    public static void thetext(String ss)
    srg=ss;     
    public static void main (String [] sfd)
        MyTest2 tr = new MyTest2();
        JFrame frame = new JFrame("Test Application");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.getContentPane().add(tr.getMainPanel());
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
        tr.intoResponse("fdgdh");
        tr.intoResponse("\n");  // if you want a new line
        tr.intoResponse("12222");
        System.out.println(srg);
class MyTest2 implements  ActionListener
    private JPanel mainPanel = new JPanel();
    private JTextArea ra = new JTextArea(5, 40);
    JButton cbt= new JButton("Send");
    JTextField cmess = new JTextField(6);
    String ss="";
    public MyTest2()
        //mainPanel.setPreferredSize(new Dimension(500, 300));
        mainPanel.setLayout( new GridLayout(4,3));
        mainPanel.add(new JScrollPane(ra));
        mainPanel.add(new JScrollPane(cmess));
        mainPanel.add(new JScrollPane(cbt));
        cbt.addActionListener(this);
    public void intoResponse(String str)
        ra.append(str);
    public void actionPerformed(ActionEvent e)
          if(e.getSource() == cbt)
               if(cmess.getText()!="")
                System.out.println(cmess.getText());
             test2.thetext(cmess.getText());
    public JComponent getMainPanel()
        return mainPanel;
}now how to take the output od "cmess.getText()" to the test2 class ? I have done it but dont think it is the right way !
as
do
System.out.println(srg);
}while (!srg.equals("stop"));
will hangs the cpu . please help. Thanks.
