Java Stream Iterator

Introduction

The following program shows how to iterate through the elements of a stream. 

// Use an iterator with a stream. 

import java.util.ArrayList;
import java.util.Iterator;
import java.util.stream.Stream;

public class Main {

  public static void main(String[] args) {

    // Create a list of Strings.
    ArrayList<String> myList = new ArrayList<>();
    myList.add("Alpha");
    myList.add("Beta");
    myList.add("Gamma");
    myList.add("Delta");
    myList.add("Phi");
    myList.add("Omega");

    // Obtain a Stream to the array list.
    Stream<String> myStream = myList.stream();

    // Obtain an iterator to the stream.
    Iterator<String> itr = myStream.iterator();

    // Iterate the elements in the stream.
    while (itr.hasNext())
      System.out.println(itr.next());
  }/* w  ww .ja  va2s  . c  om*/
}
