StringList list3 = new StringList();
      list3.add("1");
      list3.add("11");
      list3.add("1111");
      list3.add("11111");

      StringList list4 = new StringList();
      list4.add("11");
      list4.add("21");
      list4.add("111");
      list4.add("211");
      list4.add("311");

      StringList added = new StringList();
      StringList removed = new StringList();
      StringList retained = new StringList();
      ListUtil.compareLists(list3, list4, added, removed, retained);
      System.out.println("list 3: " + list3);
      System.out.println("list 4: " + list4);
      System.out.println("list added: " + added);
      System.out.println("list removed: " + removed);
      System.out.println("list retained: " + retained);

Output:

list 3: [1, 11, 1111, 11111]
list 4: [11, 21, 111, 211, 311]
list added: [21, 111, 211, 311]
