title: Referring a class on a list newbie confusion
body: <p>I was studying livewallpaper in this <a href="http://www.vogella.com/articles/AndroidLiveWallpaper/article.html" rel="nofollow">site</a>. However something there is something that i dont understand.</p>
  
  <p>Example in the code of the tutorial there a class named MyPoint</p>
  
  <pre><code>public class MyPoint {
    String text;
    private int x;
    private int y;
  
    public MyPoint(String text, int x, int y) {
      this.text = text;
      this.x = x;
      this.y = y;
    }
  } 
  </code></pre>
  
  <p>then after he created a MyWallpaperService class. Inside of that class there is a line of code like this</p>
  
  <pre><code> private List&lt;MyPoint&gt; circles;
      private Paint paint = new Paint();
      private int width;
      int height;
      private boolean visible = true;
      private int maxNumber;
      private boolean touchEnabled;
  
  public MyWallpaperEngine() {
    SharedPreferences prefs = PreferenceManager
        .getDefaultSharedPreferences(MyWallpaperService.this);
    maxNumber = Integer
        .valueOf(prefs.getString("numberOfCircles", "4"));
    touchEnabled = prefs.getBoolean("touch", false);
    circles = new ArrayList&lt;MyPoint&gt;();
    paint.setAntiAlias(true);
    paint.setColor(Color.WHITE);
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeJoin(Paint.Join.ROUND);
    paint.setStrokeWidth(10f);
    handler.post(drawRunner);
  }
  </code></pre>
  
  <p>You can see the part of code has</p>
  
  <pre><code>private List&lt;MyPoint&gt; circles;
  </code></pre>
  
  <p>This is the part that i dont understand? What is happening in here? What will <code>List&lt;MyPoint&gt;</code> pass in the circles? Anyone knows what to call this? is this list reffering to a class? Cause im not sure on my title. Thank you..</p>
