I do create objects of type Object which are very useful when using locks in multithreading applications. This perfectly answers the question, I need an object of any type that I can lock on and the first thing that comes to mind is Object

public class MultiThreadedClass{
     Object lock = new Object();
     // ...
     public void useSharedResource(){
          synchronized(lock){
              ...
          }
     }
}
