    ArrayList arrList = new ArrayList();
   
    //adding data to the list
    arrList.add("100");
    arrList.add("200");
    arrList.add("300");
    arrList.add("400");
    arrList.add("500");
   
    System.out.println("Array List elements: ");
    //display elements of ArrayList
    for(int iLoop=0; iLoop < arrList.size(); iLoop++)
      System.out.println(arrList.get(iLoop));
   
  }
}

Output

The output of the above example is:

Array List elements:
