From source file:Main.java

public static void main(String[] args) {
    Vector<Integer> firstvec = new Vector<Integer>(4);
    Vector<Integer> secondvec = new Vector<Integer>(4);

    // use add() method to add elements in the secondvec vector
    secondvec.add(5);/*from  w w w.ja  v a  2 s. c o m*/
    secondvec.add(6);
    secondvec.add(7);
    secondvec.add(8);

    // use add() method to add elements in the firstvec vector
    firstvec.add(1);
    firstvec.add(2);
    firstvec.add(3);
    firstvec.add(4);

    /** use addAll() method to add elements of the 2nd vector at 
    1st element position of the first vector */

    firstvec.addAll(1, secondvec);

    System.out.println(firstvec);
