Why wait should always be in synchronized block

What will happen if I call wait() and notify(), notifyAll() method outside of synchronization ? Does it has any effect ?

example

Class Test(){
 Test(){

I know I am writing empty try catch

   try{
      wait(); 
      notify();
      notifyAll();
   }catch (Exception ex)
  }
}

If you have an empty catch block, you'll never know what happens. Never write empty catch blocks. — Jesper, Jun 10 '11 at 08:51
@Jesper: Well, currently there isn't even an empty block. ;) — musiKk, Jun 10 '11 at 08:52

it is working fine ! I checked . But why ? – Neel Salpe Jun 10 '11 at 10:16
@Nilesh Salpe, You can't wait/notify on a object you haven't locked because that is how the lock is designed to work. – Peter Lawrey Jun 10 '11 at 11:02
