Problem accessing a objects in a public class

Question

Hello I am have written a program where I am using 2 classes. I have created a JFrame class in one of my classes and I have created a JFormattedtextfield in my other class. How do I place the JFormattedtextfields on the the JFrame which I have created in another class?

Answer 1

This is what I sort of what I mean. Since I am new to java I don't know how to mount the panels onto f here. Also the reason why I did'nt post it on the swing forum is that I got the swing part of the code figured out I just need help with the general programming bit.
public class test {
    public static void main(String[] args) {
   public test() {
          JFrame f = new JFrame("Test Program");  // f is created here
          f.setSize(400,400);
          f.setVisible(true);         
class Layout {
          //Fields for data entry
           JFormattedTextField test = new JFormattedTextField ();
           //Panels
           JPanel secondaryPanel = new JPanel();
           public Layout(){
           test.setForeground(Color.black);     
           f.add(secondaryPanel); // How do I mount this panel onto f here           
  }
