// Program to demonstrate some basic usage of ArrayLists
import java.util.*;

// old operations:
//    String[] arr         ==> ArrayList<String> list 
//    new String[n]        ==> new ArrayList<String>()   
//    String s = arr[i];   ==> String s = list.get(i);
//    arr[i] = s;          ==> list.set(i, s);
//    arr.length           ==> list.size()
// new operations:
//    list.add(s)    - add a new element to the end of the list
//    list.add(i, s) - add a new element at the given index,
//                       shifting later elements "right"
//    list.remove(i) - removes the element at the given index,
//                       shifting later elements "left"
//    list.clear()   - removes all elements of the list
