vec.add(1);
System.out.println("Added numbers are :- ");
for (Integer number : vec) {
System.out.println("Number = " + number);
}
System.out.println("Size of the vector: "+vec.size());
System.out.println("Removing all elements");
vec.removeAllElements();
System.out.println("Now size of the vector: "+vec.size());
