File creation Problem

Hello , 

                I tried to run the following code , but it is throwing out
the security exception. 

import java.applet.*;
import java.awt.*;
import java.io.*;

public class SimpleSaver extends Applet
{
        
        public void init()
        {
                Button b = new Button("Beans Book");
                b.setFont(new Font("System", Font.BOLD, 36));
                add(b);
                Saver f = new Saver(b);
                
        }


class Saver 
{

public Saver(Button b){
        
        
        try{
                        
                        FileOutputStream f = new
FileOutputStream("Sav.tmp");
                        ObjectOutput s = new ObjectOutputStream(f);
                        s.writeObject(b);
                        s.flush();                      
                        }catch(Exception e)
                         {
                                e.printStackTrace();
                                System.out.println(e);
                        }
                
                
                                }

  }

}
