// This program demonstrates how to use an ArrayList

public class ArrayListClient {
	// Translation from array to ArrayList:
	//  String[]             ArrayList<String>
	//  new String[n]        new ArrayList<String>()
	//  list[i]              list.get(i)
	//  list[i] = val        list.set(i, val);
	//  list.length          list.size()
    //
	// New operations:
	//  list.add(val)        appends val to list
	//  list.add(i, val)     inserts val at index i shifting subsequent values to the right
	//  list.remove(i)       removes and returns the value at i
	//  list.clear()         clears the entire ArrayList
