title: Map values to ArrayList
body: <p>I have a <code>Map&lt;Integer, MyClass&gt;</code> and <code>MyClass</code> has 2 fields, <code>Object1 obj</code> and <code>Object2 objj</code> for example.</p>
  
  <p>How can I create an <code>ArrayList&lt;Object2&gt;</code> with all <code>Object2</code> values?</p>
  
  <p>Must I iterate the <code>Map</code> and then add the values to the <code>ArrayList</code> or exists another way?</p>
