Usage

From source file:ArraySet.java

public static void main(String args[]) {
    String elements[] = { "A", "B", "C", "D", "E" };
    Set set = new ArraySet(Arrays.asList(elements));
    Iterator iter = set.iterator();
    while (iter.hasNext()) {
        System.out.println(iter.next());
    }/*from   w w  w  .  ja  v a  2s  . c o  m*/
}

From source file:ArraySet.java

public static void main(String args[]) {
    String elements[] = { "Java", "Source", "and", "Support", "." };
    Set set = new ArraySet(Arrays.asList(elements));
    Iterator iter = set.iterator();
    while (iter.hasNext()) {
