This Java example shows how to iterate Java ArrayList using Iterator.

import java.util.ArrayList;
import java.util.Iterator;
 
//Iterate Java ArrayList
public class IterateJavaArrayList {
    public static void main(String args[]){
       
        //create new ArrayList
        ArrayList<String> aListNumbers = new ArrayList<String>();
        aListNumbers.add("1");
        aListNumbers.add("2");
        aListNumbers.add("3");
       
        /*
         * To iterate Java ArrayList use,
         * Iterator iterator()
         * method of Java ArrayList.
         */
       
        Iterator<String> itr = aListNumbers.iterator();
       
        //iterate Java ArrayList using Iterator
        while(itr.hasNext()){
            System.out.println(itr.next());
        }
    }
}
 
/*
Output of above given Iterate Java ArrayList would be
1
2
3
*/
