title: Checking if an ArrayList contains a certain String while being case insensitive
body: <p>How can i search through an ArrayList using the .contains method while being case insensitive? I've tried .containsIgnoreCase but found out that the IgnoreCase method only works for Strings.</p>
  
  <p>Here's the method I'm trying to create: </p>
  
  <pre><code> private ArrayList&lt;String&gt; Ord = new ArrayList&lt;String&gt;(); 
  
   public void leggTilOrd(String ord){
       if (!Ord.contains(ord)){
           Ord.add(ord);
       }
   }
  </code></pre>
