Usage

From source file:Main.java

public static void main(String[] args) {
    List<String> list = Arrays.asList(args);
    Collections.sort(list);
    System.out.println(list);/*ww w .ja va 2s  .  c  om*/
}

From source file:MainClass.java

public static void main(String args[]) throws Exception {
    List list = Arrays.asList("a", "c", "b");
    Collections.sort(list);
    for (int i = 0, n = list.size(); i < n; i++) {
        if (i != 0)
            System.out.print(", ");
        System.out.print(list.get(i));
    }/*from  ww w  .j a va2 s  .c  o  m*/
    System.out.println();
}

From source file:MainClass.java

public static void main(String[] a) {
    List list = new ArrayList();
    list.add("A");
    list.add("C");
    list.add("B");
    Collections.sort(list);
    System.out.println(list);//from ww  w  . j a  v a 2s .  c o m
}

From source file:MainClass.java

public static void main(String args[]) {
    Vector v1 = new Vector();
    v1.add("A");/*w  ww . ja v  a 2 s. c o  m*/
    v1.add("C");
    v1.add("B");
    Vector v2 = (Vector) v1.clone();
    Collections.sort(v2);

    System.out.println(v1);
    System.out.println(v2);
}

From source file:Main.java

    Collections.sort(list, Collections.reverseOrder());

    Collections.sort(list, String.CASE_INSENSITIVE_ORDER);
    Collections.reverse(list);//from   w  ww.  j  a v  a 2 s .c  om
}

From source file:Main.java

public static void main(String[] args) {

    Vector v = new Vector();

    v.add("1");/*  w ww. j av  a 2s  . c o  m*/

    v.add("4");

    Collections.sort(v);

    for (int i = 0; i < v.size(); i++)
        System.out.println(v.get(i));

}

From source file:Main.java

    String[] strArray = new String[] { "z", "a", "A" };
    List list = Arrays.asList(strArray);

    Collections.sort(list);

    Collections.sort(list, String.CASE_INSENSITIVE_ORDER);

    Collections.sort(list, Collections.reverseOrder());

    Collections.sort(list, String.CASE_INSENSITIVE_ORDER);
    Collections.reverse(list);/*  www . ja va2 s  .  c o  m*/
}

From source file:Main.java

public static void main(String[] args) {
