title: Java reflection: how to get field value from an object, not knowing its class
body: <p>Say, I have a method that returns a custom <code>List</code> with some objects. They are returned as <code>Object</code> to me. I need to get value of a certain field from these objects, but I don't know the objects' class. </p>
  
  <p>Is there a way to do this via Reflecion or somehow else?</p>
