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

public class Main {
  public static void main(String[] args) {
    ArrayList<String> aList = new ArrayList<String>();

    aList.add("1");
    aList.add("2");
    aList.add("3");
    aList.add("4");
    aList.add("5");

    for (String str: aList) {
      System.out.println(str);
    }
    Iterator itr = aList.iterator();

    // remove 2 from ArrayList using Iterator's remove method.

    String strElement = "";

    while (itr.hasNext()) {
      strElement = (String) itr.next();
      if (strElement.equals("2")) {
        itr.remove();
