Example 1: java loop through arraylist

ArrayList<String> namesList = new ArrayList<String>(Arrays.asList( "alex", "brian", "charles") );
         
for(String name : namesList)

Example 2: 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());
      }
   }
}
