title: How to remove specific entries from Firebase in Android Studio?
body: <p>I have the following structure in Firebase:
  <a href="https://i.stack.imgur.com/qxkL0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qxkL0.png" alt="Structure in Firebase"></a></p>
  
  <p>where the entries contain an <code>image</code> and a <code>timestamp</code>. The name of each entry is randomly generated and the <code>timestamp</code> is an int larger than 0.</p>
  
  <p><strong>What I want:</strong></p>
  
  <p>To delete the entries with a <code>timestamp</code> smaller than a specific value.</p>
  
  <p><strong>My current progress:</strong></p>
  
  <p>I should be able to retrieve the list of sorted entries with the following code:</p>
  
  <pre><code>Firebase myFirebaseRef = new Firebase("https://someURL.firebaseio.com/");
  Firebase listOfObjects = myFirebaseRef.orderByChild("timestamp").getRef();
  </code></pre>
  
  <p><strong>What's next:</strong></p>
  
  <p>I want to iterate through and/or somehow only remove specific entries in the <code>listOfObjects</code>. Possibly with some if-statements?</p>
