This segment of tutorial illustrates about the Vector class and its use with the Iterator interface.We will create an example to print the content of the a Vector.

• Vector is a collection class.It works similar to the Array.
• It has growable array.Its size may increase or decrease.
• It has iterator() method.So Iterator interface can traverse all its elements.

Java Vector Iterator with Example

import java.util.Iterator;
import java.util.Vector;

public class vector {

	public static void main(String[] args) {
		Vector v = new Vector();
		String city[] = { "delhi", "hongkong", "dubai", "sanghai" };
		for (String s : city) {
			v.add(s);
		}
		Iterator it = v.iterator();
		for (; it.hasNext();)
		System.out.println(it.next());
	}
}

Output
