		vector.add("D");
		
		System.out.println("Before removing all elements , Vector contains : ");
		for(int index=0; index < vector.size(); index++) {
			System.out.println(vector.get(index));
		}
		
		/*
		 * To remove all elements from the Vector use  clear method.
		 */
		vector.clear();
		
		System.out.println("After removing all elements , Vector contains : ");
		for(int index=0; index < vector.size(); index++) {
			System.out.println(vector.get(index));
