Usage

From source file:Main.java

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

    System.out.println(set.isEmpty());
}

From source file:Main.java

public static void main(String[] args) {
    String[] peoples = { "A", "B", "C", "D", "E", "F" };
    List<String> names = Arrays.asList(peoples);

    for (int i = 0; i < peoples.length; i++) {
        int index = new Random().nextInt(names.size());
        String anynames = names.get(index);
        System.out.println(anynames);

    }//from   ww  w  .j  a  va 2s . c  o  m

}

From source file:Main.java
