title: Sort a LinkedList of objects by object's variable
body: <p>Here is my problem, I have a <code>LinkedList</code> of objects, which have a <code>String</code> name and an <code>int</code> score value.</p>
  
  <p>Now, I need to sort this list in descending order based on the score value.</p>
  
  <p>How do I do that? I tried with <code>Collections.sort(List)</code>, but that doesn't work with objects. </p>
  
  <p>How do I tell Java to use the score as the value to comparison?</p>
