how to interate through a list in methods of a class code example

Example: traversal of list in java

import java.util.ArrayList;
import java.util.Iterator;

public class IteratorSample {
   public static void main(String[] args) {
      ArrayList<String> list = new ArrayList<String>();
      list.add("JavaFx");
      list.add("Java");
      list.add("WebGL");
      list.add("OpenCV");
      Iterator iterator = list.iterator();
      while(iterator.hasNext()) {
         System.out.println(iterator.next());
      }
