Java 集合 向LinkedList添加元素

import java.util.LinkedList;
class LinkedListAdd {

  public static void main(String[] args) {

     // create a LinkedList
     LinkedList<String> list = new LinkedList<String>();

     // Adding elements to the LinkedList
     list.add("Harry");
     list.add("Ajeet");
     list.add("Tom");
     list.add("Steve");

     // Displaying LinkedList elements
     System.out.println("LinkedList elements: "+list);

     // Adding another element
     list.add("Kate");

     // Displaying LinkedList elements after add(E e)
     System.out.println("LinkedList elements: "+list);
  }
}
