Vector<Integer> secondvec = new Vector<Integer> (4);
// use add() method to add elements in the secondvec vector
secondvec.add(5);
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 secondvec with firstvec vector
firstvec.addAll(secondvec);
// let us print all the elements available in vector firstvec vector
