What will be the output of the program?

public class Test 
 {    
    public static void main (String [] args)      
    {      
       final Foo f = new Foo();         
       Thread t = new Thread(new Runnable()      
       {       
          public void run()      
          {             
              f.doStuff();       
          }        
       });      
       Thread g = new Thread()       
       {        
          public void run()           
          {        
              f.doStuff();        
          }     
       };    
       t.start();      
       g.start();  
   } 
 } 
 class Foo 
 {   
       int x = 5; 
       public void doStuff()    
       {        
            if (x 10)          
            {            
              // nothing to do               
              try           
              {          
                  wait();                 
            } catch(InterruptedExcepx) { }         }     
else

    }
