Example 1

import java.util.*;
public class VectorIteratorExample1 {  
	public static void main(String arg[]) {	
		//Create an empty Vector      
		Vector < String > colors = new Vector < String > ();
		//Add color elements in the vector
            colors.add("Red");
            colors.add("Green");
            colors.add("Blue");
            colors.add("Pink");
            //Obtain an Iterator
            Iterator<String> itr = colors.iterator();
            while(itr.hasNext()){
                 System.out.println(itr.next());
            }
