java arraylist to iterator code example

Example 1: ArrayList iterator() method in java

import java.util.ArrayList;
import java.util.Iterator;
public class ArrayListIteratorMethodExample
{
   public static void main(String[] args)
   {
      ArrayList<String> fruits = new ArrayList<String>(7);
      fruits.add("banana");
      fruits.add("mango");
      fruits.add("apple");
      fruits.add("watermelon");
      fruits.add("pineapple");
      fruits.add("orange");
      fruits.add("plum");
      Iterator<String> iterate;
      iterate = fruits.iterator();
      System.out.println("Fruits in ArrayList are: ");
      while(iterate.hasNext())
      {
         System.out.println(iterate.next());
      }
   }
}

Example 2: how to convert arraylist to iterable in java

Integer[] myArray = {897, 56, 78, 90, 12, 123, 75};
Iterator<Integer> iterator = Arrays.asList(myArray).iterator();

//Iterator<Integer> iterator = Arrays.stream(myArray).iterator();
while(iterator.hasNext()) {
   System.out.println(iterator.next());
}
