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)
  }
}

You get an IllegalMonitorStateException,

IllegalMonitorStateException - if the current thread is not the owner of the object's monitor.
