  Shuffle elements of Java Vector example
  This java example shows how to shuffle elements of Java Vector object using
  shuffle method of Collections class.

  public static void main(String[] args) {
 
    //create a Vector object
    Vector v = new Vector();
 
    //Add elements to Vector
    v.add("1");
    v.add("2");
    v.add("3");
    v.add("4");
    v.add("5");
 
    System.out.println("Before shuffling, Vector contains : " + v);
 
    /*
      To shuffle elements of Java Vector use,
      static void shuffle(List list) method of Collections class.
    */
 
    Collections.shuffle(v);
 
    System.out.println("After shuffling, Vector contains : " + v);
 
  }
}
 
/*
Output would be
Before shuffling, Vector contains : [1, 2, 3, 4, 5]
After shuffling, Vector contains : [4, 3, 2, 1, 5]
