    Default Problem while getting a number from another thread

    Hi,
    I have got a problem. I need get a number from another thread for example this code:
    package vyjimky;
     
    /**
     *
     * @author Lolek
     */
    public class Main {
     
        /**
         * @param args the command line arguments
         */
        public static void main(String[] args) {       
        Thread1 vlak = new Thread1();
        Number bolo = new Number();
     
        vlak.k.start();
     
     
     
    }
    }
    class Thread1 implements Runnable
    {   
        private Number save = new Number();
        int i;
        Thread k;
        Vlakno (){
            k = new Thread(this,"vlakno");
        }
       public void run ()
        {
        i = 10; 
        save.setData(i);
        }
    }
    class Number
    {
