Linked Lists

• Collection

  container that stores objects
• list

  ordered collection of elements; list size grows and shrinks as elements are removed
• LinkedList

  stores elements in a doubly linked list
• LinkedList object creation

  import java.util.LinkedList;

  LinkedList<String>toDoList=newLinkedList<String>();

  LinkedList<Integer>parkingSpacesList=newLinkedList<Integer>();
• LinkedList iterator


  import java.util.Iterator;

  Iterator<String>iterator=toDoList.iterator();

  
  

  while(iterator.hasNext())

  {

  System.out.println(iterator.next());

  }
• enhanced for loop option to traverse all elements in the collection

  for(String element: toDoList) // For each String element in toDoList{System.out.println(element);}
