Usage

From source file:Main.java

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");

    ListIterator<String> listIterator = aList.listIterator();
    listIterator.next();//from   w ww  .  j a  va 2  s  .  c  o  m

    listIterator.set("100");
    for (String str : aList) {
        System.out.println(str);
