Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    String[] strArray = new String[] { "z", "a", "A" };
    List list = Arrays.asList(strArray);

    Collections.sort(list);//from  w  w w  . j  ava 2 s. c  o  m

    Collections.sort(list, String.CASE_INSENSITIVE_ORDER);

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

    Collections.sort(list, String.CASE_INSENSITIVE_ORDER);
    Collections.reverse(list);
}

From source file:Main.java

public static void main(String[] a) {
    String elements[] = { "A", "B", "C", "D", "E" };
    HashSet<String> set = new HashSet<String>(Arrays.asList(elements));

    Object[] arrObj = set.toArray();

    for (int i = 0; i < arrObj.length; i++) {
        System.out.println(arrObj[i]);
    }//from ww w.ja v  a 2s. co  m

    System.out.println(set);
}
