Transfer of the variable through JComboBox

Question

Hello people,
I have the following question. In the main JFrame class i put on the JPanel JComboBox. Depending on the values i choose with the help of JCombobox, my following program shoud change the behavior, then in one of classes which is called from another class i use the chosen value.
so, should i again call main class in one of subclasses with the aim to transfer of the given value.? When i call the main the program was hanging,
Thank you in advance

My
AnimatorFrame.class calls 2 classes
Animator11 and Animator33
Animator33 calls ReadFile.class, but the value (the name of the file is defined in the AnimatorFrame ,
i see only one way to call Animator33(filename), which calles the ReadFile(filename)
Finally my main program doesn't work, what wrong with it?
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class AnimatorFrame extends JFrame implements ActionListener
     Animator11 an1;
     Animator33 an3;
       JButton okbutton,endbutton;
        JPanel buttonPanel;
     public AnimatorFrame() {
          super("Animator");
          addWindowListener(new WindowDestroyer());
          createComponents();
          pack();
          setVisible(true);
     private void createComponents() {
          Container c=getContentPane();
                buttonPanel=new JPanel();
                okbutton=new JButton("Start");
                endbutton=new JButton("Stop");
          buttonPanel.add(okbutton,BorderLayout.CENTER);
                buttonPanel.add(endbutton,BorderLayout.CENTER);
                an1=new Animator11();
          an3=new Animator33();
          an1.setLayout(new BorderLayout());
          an1.add(an3, BorderLayout.NORTH);
                an1.add(buttonPanel,BorderLayout.CENTER); 
          c.add(an1, BorderLayout.SOUTH);
     public void startAnimation() {
          an1.start();
          an3.start();
         public void actionPerforme(ActionEvent e)
   if(e.getActionCommand().equals("Start"))
      this.startAnimation();
   if(e.getActionCommand().equals("Stop"))
    System.exit(0);
     public static void main(String[] args) {
          AnimatorFrame f=new AnimatorFrame();
                f.createComponents();
                f.setVisible(true);
//          f.startAnimation();
}It gives animator class must be declared abstract!
i didn't present here ComboBox problem......
