    copied!<p>I am supposed to write a program that makes entries in a gift registry. User can enter as many gift item desired and the store where this can be purchased. Once the user express desire to stop entering a new item, a summary of all the gift item &amp; stores will be displayed.</p> <pre><code>Below is a sample output Do you wish to make a gift registry list? (y/n): y Enter item: watch Enter store: Swatch Any more items? (y/n): y Enter item: ballpen Enter store: National Bookstore Any more items? (y/n): n Gift Registry: watch - Swatch ballpen - National Boo </code></pre> <p>If I'm not mistaken, I am supposed to make use of arrays for this program right? Is it possible to have a length of an array dependent on the counter(the number of times the user inputs)?</p> <p>So far these are my codes:</p> <pre><code>package arrays; import java.util.*; import java.util.List; import java.util.ArrayList; public class GiftRegistry { public static void main (String[] args) { Scanner input = new Scanner(System.in); String choice; // Declare array num ArrayList&lt;String&gt; items = new ArrayList&lt;String&gt;(); ArrayList&lt;String&gt; stores = new ArrayList&lt;String&gt;(); items.add(items); stores.add(stores); System.out.print("Do you wish to make a gift registry list? (y/n):"); choice = input.nextLine(); while (choice.charAt(0) != 'n') { System.out.print("Enter item: "); items.add(items) = input.nextInt(); System.out.print("Enter store: "); stores.add(stores) = input.nextInt(); System.out.print("Any more items? (y/n):"); choice = input.nextLine(); } System.out.println("Gift regisrty: "); } } </code></pre> <p>I really don't know how</p>
