Clarity

• Confused programmers write buggy code
• Bad example: Removing elements from LinkedList
  
• Reminder: Standard linked list class
  

  LinkedList<String> countries = new LinkedList<String>(); 
  countries.add("A"); 
  countries.add("B"); 
  countries.add("C"); 
  

• Iterate through list:
  

  ListIterator<String> iterator = countries.listIterator(); 
  while (iterator.hasNext()) 
     System.out.println(iterator.next());
