title: I need to hold multiple int values in a Map
body: <p>I need to create a book index method which can pair multiple values to one key</p>
  
  <p>e.g
  key - "Beck,Kent"
  value - 27 23 76</p>
  
  <p>is this possible?</p>
  
  <p>the import ou.*; is the Open University library and should not affect anything.</p>
  
  <pre><code>import java.util.*;
  import ou.*;
  public class BookIndex
  {
  
  public Map&lt;String, Integer&gt; index()
  {
     Map&lt;String, Integer&gt; actual = new HashMap&lt;&gt;();
     return actual;
  }
  </code></pre>
  
  <p>Thanks</p>
