show the content of set

Iterate on a java set object . Iteration in this example use of Long objects . Actually the code is so simple to understand ,but the idea is used so frequent.

Code:

    public void showSetOntent(Set<Long> setLongs){
        if(setLongs==null || setLongs.isEmpty()){
            return;
        }
        
        Iterator<Long> iterator = setLongs.iterator();
        while(iterator.hasNext()){
            System.out.println("Show current content = "+iterator.next());
        }
        }
