	    //create Vector. 
	    Vector vector = new Vector();
	    
	    vector.add("A");
	    vector.add("B");
	    vector.add("C");
	    vector.add("D");
	    
	    /*
	     * To add an element at the specified index of Vector use add(int index, Object obj) method.
	     */
	    vector.add(1,"X");
	    System.out.println("After add an element X to vector, vector contains :");
	    for(int index=0; index < vector.size() ; index++) {
	    	System.out.println(vector.get(index));
