Usage

From source file:Main.java

public static void main(String args[]) {
    HashSet<String> hs = new HashSet<String>(20);

    hs.add("java2s.com");
    hs.add("j a v a2s.com");

    System.out.println(hs);//from  w  w w.j ava2  s.  co  m
}

From source file:Main.java

public static void main(String[] args) {

    HashSet<String> months = new HashSet<String>(24);

    Collections.addAll(months, DateFormatSymbols.getInstance().getMonths());
    Collections.addAll(months, DateFormatSymbols.getInstance().getShortMonths());

    System.out.println(months.contains(args[0]));

}

From source file:Main.java

public static void main(String[] argv) throws Exception {
    int[] array = new int[10];

    Set set = new HashSet(Arrays.asList(array));
}

From source file:Iterate.java

public static void main(String args[]) {
    String elements[] = { "Irish Setter", "Poodle", "English Setter", "Gordon Setter", "Pug" };

    Iterator iter = set.iterator();
    while (iter.hasNext()) {
        System.out.println(iter.next());
    }/*from   w w  w . ja v  a 2 s  . com*/
}
