class ClassA{
JFrame frame;
JTextField text1;
void form()
{
frame=new JFrame("test");
JPanel cp=new JPanel();
text1=new JTextField(10);
cp.add(text1);
frame.add(cp);
frame.setSize(300,100);
frame.setVisible(true);
}
}

class ClassB implements ActionListener
{
JFrame f;

public static void main(String args[])
{
ClassB s=new ClassB();
s.form();
}
void form()
{
text=new JTextField(10);
jb=new JButton("Submit");
f=new JFrame("test");
JPanel cp=new JPanel();
cp.add(text);
cp.add(jb);

jb.addActionListener(this);

f.setSize(300,100);
f.setVisible(true);
f.add(cp);
}
public void actionPerformed(ActionEvent ae)
{
m=new ClassA();
m.form();
m.text1.setText(text.getText());
}
