title: How to: Make addition to class property within list
body: <p>I have a <code>List&lt;Presenter&gt; presenterList;</code></p>
  
  <p>With </p>
  
  <pre><code>public class Presenter(){
    String name;
    String imageRef; // Filename to be downloaded
    Bitmap image;
  
    (etc...)
  }
  </code></pre>
  
  <p>I'm working with AsyncTask &amp; once the image has downloaded, I wish to go through the list and set Image value to the newly download image.
  so far i have</p>
  
  <pre><code>Presenter pres = PresenterList.get(Position);
  pres.Image = new (Bitmap) downloadedImageFromImageRef;
  </code></pre>
  
  <p>however i fear that this will not relate to the Image value of the presenter within the list.</p>
  
  <p>How do i refer, or even assign to the specific Presenter attribute within the list?</p>
  
  <p>From working with C (many years ago), i belive somthing like a pointer to the value in which to assign .Image would work</p>
  
  <p>Thank you in advace</p>
