Usage

From source file:Main.java

public static void main(String[] args) {
    Queue<String> queue = new LinkedList<String>();
    queue.add("Hello");
    queue.add("World");
    List<String> list = new ArrayList<String>(queue);

    System.out.println(list);/*from  w w w .j  av a2  s . c  o m*/
}

From source file:Main.java

public static void main(String args[]) {
    String init[] = { "One", "Two", "Three", "One", "Two", "Three" };

    // create two lists
    List<String> list1 = new ArrayList<String>(Arrays.asList(init));
    List<String> list2 = new ArrayList<String>(Arrays.asList(init));

    // remove from list1
    list1.remove("One");
    System.out.println("List1 value: " + list1);

    // remove from list2 using singleton
    list2.removeAll(Collections.singleton("One"));
    System.out.println("The SingletonList is :" + list2);
}

    System.out.println("List value before: " + list);

    // sort the list
    Collections.sort(list);/*from w  w w  .  j  a v a2 s  .  co  m*/

    System.out.println("List value after sort: " + list);
