Java Vector class

Unique features of Vector

Vector appears earlier, earlier than collections

1: add functionality

 public void addElement(Object obj);// with add() alternative

2: get function

public Object elementAt(int index);// with get() alternative
public Enumeration elements();// Returns the object of the implementation class Iterator iterator()

import java.util.Enumeration;
import java.util.Vector;
